Review: Quality product - It’s straight forward, metal plates, good quality, hopfully ill never have to see if they survive a fire. Metal lunch that comes with it works fine all be it low quality. I purchased a nemco for less than $10 but the one that’s included works just fine.
Review: Preliminary review - Not a full review but just some things i've noticed that some people will want to know about. -It is thick and heavier than expected. Definitely not something you want to carry around but i like that it feels so substantial. -The included punch is unreliable. Doesn't always spring actuate. 50% success rate -Even though it's made out of steel, it's not very magnetic. If you put your average fridge magnet on it, it will barely stay on. If you use a rare earth magnetic, it will stick better but is still very weak. So if you're thinking of hiding this wallet somewhere using a magnet, then this is not the wallet to get.

## Features

### ⭐⭐⭐⭐ Good plates, bad punch
*by T***Y on August 20, 2025*

Nice concept and quality steel plates. The punch is a problem. It worked well for the first few words but then failed. I found unscrewing the different components and then applying very slow, steady pressure helped it to work better, though I had to do that several times throughout the process. I suspect the failure has to do with a misalignment of the internal piston. So, be patient with the punch or have another punch to use to mark the plates.
