Ice Cube Tray for Tumbler Cup 30Oz-40Oz, 3 Pcs Silicone Cylinder Ice Mold with Lid and Bin for Freezer, Easy Fill and Release Ice Maker for Whiskey, Cocktail BPA-Free (Black, 40Oz-Type2)

This thing is genius. Keeps my water colder, longer and I have no issues getting my straw in! It’s a little bit of a pain to get the cubes out, but I can overlook it since it is so functional! Loved it so much I got one for all my co-workers for Christmas!

I bought this ice cube tray as a Christmas gift for my daughter, and she absolutely loved it. It fits perfectly in her 40 oz tumbler and makes long cylinder ice that lasts much longer than regular cubes. The silicone is flexible, so the ice is easy to remove, and the lid helps prevent spills in the freezer. The bin is a nice bonus for storage too. Overall, it’s well made, easy to use, and a great gift idea for anyone who uses large tumblers daily. Highly recommend!

This ice cube tray makes great ice cubes that last all day. After filling the outer container with hot water for a few seconds, the silicone mold is flexible enough to easily unfold and pull the cube out. The lid for this particular mode doesn't quite stay on well. I purchased the green one as well and I do not have this same problem. The fact that the lid doesn't stay on, doesn't effect the functionality of the tray making the ice cubes.

I bought this set for my girlfriend’s adult daughter because she kept stealing my ice, but she hasn’t used it yet. Luckily, it fits perfectly in my own 30oz–40oz tumbler cups, so it’s still a win for me. The silicone trays are high quality and make filling and releasing ice really simple. The included lids prevent spills and freezer odors, and the storage bin keeps everything organized. Shipping was quick and the packaging was clean and secure. For the price, you get a lot of value — three trays, lids, and a bin. It’s BPA-free, easy to clean, and makes ice that’s just the right size for big cups, whiskey, or cocktails. Overall, I’m really happy with this purchase and would definitely recommend it for anyone who uses larger tumblers or just wants hassle-free ice making.

Very useful and fantastic for Stanleys and the like. The largest ring won't likely fit a 32 oz or smaller. But the ice is thick, lasts a long time, and can go into any kind of glass. It is easy to get the ice out and refill. It comes with a box so your ice doesnt get freezer smell and the water doesnt spill all over. Great idea.

Love this product. We favor the mid sized ice ring for our thermoses. The ice rings are a bit difficult to get out of the tray but overall like this product.

A little too cold to handle when it comes out of freezer but love the idea and for sure keeps my water cold!

This is by far one of my favorite purchases! I hate when you put ice in your Stanley or hydro and have to fight your straw through the ice! This makes the perfect size, hollow ice cubes that your straw slides easily in. It’s really easy to clean, is flexible for easy storage but also comes with its own storage Tupperware. Oh and it didn’t change the taste of my water so BIG plus and the ice lasted me through to the next morning!
