## Description

The Kuru Toga Roulette Has A Ring Design On The Grip For An Ergonomic Hold And Balanced Weight. Features The Same Excellent Kuru Toga Lead Rotation System Inside. It'S Going To Take A True Pencil Expert To Understand The Common Pencil'S Dilemma But Hang In There As We Try And Explain. With Standard Mechanical Pencils, As You Write The Pencil Lead Is Worn Down Until It Is A Slanted Surface. Each Time You Write You Will Get A Different Experience Depending On How The Pencil Is Rotated. This Can Cause Multiple Annoyances: 1. As You Start To Write You Might Have A Sharp Point, But As You Continue To Write The Point Is Worn Down And Thus Your Line Widths Are Not Uniform. This Can Also Lead To Smudgy And Thick Lines. 2. If You Pick The Pencil Up And Happen To Start Writing With The Tip Of The Angled Point, It Is Likely To Scratch Or Catch On The Paper. 3. The Different Angles At Which The Pencil Lead Comes In To Contact With The Paper Is A Common Cause Of Lead Breakage. The Kuru Toga, On The Other Hand, Has A Core Rotation Mechanism That Continually Rotates The Pencil Lead As You Write. The Lead Is Twisted Through A Spring-Loaded Clutch, It Works By Twisting Incrementally Every Time You Lift The Pencil Up (I.E. During Printing Words, Etc.). This Allows A Uniform Wearing Of The Pencil Lead So That It Always Remains As A Pointed Tip. Not Only Does It Solve The Above Problems, But It Also Gives You An Amazingly Thin Line. You Are Effectively Using Only 50% Of The Lead Area That You Were Previously Using With Your Old Mechanical Pencil. Thus, A 0.3 Mm Kuru Toga Will Write Incredibly Thin Lines And Have Less Breakage Than A Standard 0.3 Mm Mechanical Pencil.

Review: Great for daily studies, durable and premium - This pencil has served as a daily driver when studying, and feels more premium than the standard kuru toga model. While this model is not completely metal as some would expect, I am okay with the fact that only the knurling and the tip are metal-- the barrel is plastic. The weight of the pencil is nice, and not too heavy (lighter than the graphgear 1000). I have used this pencil for long study sessions of topics that require precise writing, and it is very accurate due to the long metal barrel tip. I would not recommend throwing the pencil quickly in a backpack, as the tip may bend when not cared for properly. This pencil is easy to use, and many diagrams exist online if ever needed to repair. The rotating lead mechanism works perfectly and feels most similar to the original mechanism. I will continue to recommend this pencil to people who want the Kuru Toga with a more premium feel.
Review: Yes, it is as good as it looks! - Ok, normally I have to write extended reviews to not only give praise to its features and accomplishments, but also to give a run down on all of their issues and sub par materials. This Mech, I have to say, is one fine pencil. It isn’t just a great design, it is also technically very sound and I found no bad issues whatsoever. The materials used in the build are all high end. The fittings are masterly snug. And even pulling a line with this pencil feels amazing. Holding this mech in your hand, you can feel the significant difference from how most other pencils feel. This Pencil feel high end. The grip is a hybrid of knurling and grooves. The tip is a little on the large size, but the tubular steps are brilliantly sized with the first step down being sized perfectly for those of us who tend to choke up on pencils when going in for the fine detail. The needle tip holds the lead very firm and stable. There is no excessive play in the needle that would cause flex/bowing or lead chattering. For those of you wondering what that means. When a needle has a little too much excessive play inside, the lead can slightly bounce causing a micro chattering effect you can feel. When the needle has way too much excessive play, it causes the lead to flex and bow easily breaking leads often, also causing precision issues when the lead jumps around in the needle during lay down and lift off of paper. This “UNI” mech has none of those issues. The lead spiraling function they added to always help keep the lead stay sharp by spinning, works great. And it has a small window on the grip to show that the function is working inside. The lead advancement is about 0.3 to 0.4mm per click. Making it easier to fine tune the perfect length for individuals. Now this Mech isn’t balanced, but Mechs don’t need to be balanced. Not sure why some people get caught up in feeling they need it to be. So I just go Ahead and add that on my list of check points for others. Although, it never holds weight in my reviews and should never be a deciding factor for any user, just as the erasers on Mechs should never be taken into account. I do reviews for real people, Not little children that gets upset cause they have trouble with, or replacing the erasers that they really don’t need to be using in the first place. Personally speaking, if I was to ever design my own Mechanical Pencil, it wouldn’t even have an eraser. Grow up and buy a separate eraser. Now, let’s get back to the review. This is where I normally have to leave a real complaint about how a clicker head is loose and feels like it moves around to much. But, this clicker head feels ok. Sure it has a small amount of lateral play, but far from being bad. Plus the push clutch feels nice and firm when pushing it in. And I guess I should add that it has a nice strong feeling clip on this mech, though, I will also add that a clip on a mech is another overrated addition people feel the need to care about. I have never found a time that I was glad that my mech had a nice clip. Haha. Your mech should never be slid into your pocket where it would need that clip. This is not a pen. You shouldn’t be just carrying it around like you will need to be signing your signatures with. If it needs to go with you some place, then put it in a closing pencil pouch, pencil roll, case, or something that protects it. Not just shoved in a pocket like a cheap Bic pen. All this aside... let’s finish up this review by letting me tell you that I would highly suggest buying this Mech. I seriously couldn’t really find anything wrong with it. It is easily capable of being on a list of some of the best Mechs on the market. On top of the fact that it isn’t expensive. So you have a great pencil at a great price. This is definitely one to put in your collection. It’s a 5 star Mech.

## Questions & Answers

**Q: Does the tip retract? I'm worried about putting it in my pocket.**
A: It does not retract. I've got three of these for each jacket I wear so I don't worry about forgetting to take a pencil. So far no problems with the tip...

**Q: is the body and cap a metal material**
A: No the body and eraser cap are plastic material. However the grip, the end cap, and the lead sleeve seem to be metal.

**Q: Do you need to buy a special kind of lead for it?**
A: Any 0.5mm lead will work, but the specific Kurotoga lead is softer on the outside and is purportedly more effective with the mechanism.  For very dark writing, I prefer Neox lead but it can smudge/smear a little.  My second favorite is Ain Stein lead, which almost never smudges and lasts a little longer (not quite as soft as Neox).

**Q: How durable is this? I am a graduate student in EE and math and break so many of the best mechanical pencils from staples and other office stores.**
A: I actually bought this mp to add to my mechanical pencil collection.  I now have about eight mps, all different.  Therefore, I could not provide any info regarding its durability.  I can say that this is a beautiful, finely crafted instrument.  It may be the best in terms of appearance.  I really don't think you would go wrong if you selected this one.  Best of luck!!

### ⭐⭐⭐⭐⭐ Beautiful Pencil with Some Flaws
*by P***. on December 20, 2017*

First off this is an expenisve pencil. Period no doubt about it, it's pricey. But once you get it you'll understand why. Every where I go, and use this people look at me, and say "Woah that's nice." Trust me when I say this "This is a sexy pencil!" It is beyond the best looking mechanical pencil I've ever used. But no matter the look that's still a hefty price. It's justifiable though. The mechanism inside turns as you write. It may sound relatively simple, but it's super handy. Personally I print, so as I write it tends to dull out on one side, so I have to turn my pencil to get a sharp tip to write on. This however completely elimaninates that. The best part though for me is the little circle cut out that actually lets you see the turning. It's pretty darn cool. Their is something that really does p*** me off, and that's the eraser. That thing is barely a centimeter, and truly sucks at being an eraser. I used this two days in math, and it was barely a stub by the third day of school. So if your planning to buy keep an eraser handy. Even though it looks good it has another major body flaw. And that's the clip part. That section of the pencil is plastic, and it will peel/scratch like it did to mine. Apart from that the rest of the pencil is made from metal. It really gives it that high end feel. If you are gonna buy this I can't stress enough that you should go with their led. The Kuro Tuga led it personally for me a lot tougher? It's led, I know, how can it be tough? If you use this led, and press down their is as huge difference from other leds. You'll feel the diference when your writing. I have personally bought their led, and am currently in highschool. I have science, math, french, and English, and have only run though three rolls (currently on the third). Oh and we've reached the end of the secound quarter, so those three rolls lasted me half a school year. And those are prettty writing intensive classes, so I guarantee it'll last you a while. Overall though this is an amazing pencil. It looks great, writes like butter, and it will last you as of write now probably an entire school year of intensive everyday writing. Pricey but defenitily worth the buy. You won't be dissapointed. And if you found this useful in anyway hit that helpful button for me. Have a great day !
