Ice Cube Tray for Stanley Cup Tumblers 30-40oz, Silicone Ice Cube Molds with Lid and Bin, Easy Release Ice Maker for Chilling Cocktails, Coffee, Drinks, BPA Free(Green)

I bought this for my 40 oz tumbler. It takes a few times of using it to get used to your fingers freezing as you pop out the ice. Ive learned that if you push down the center of the molds and let it separate from the ice, they will pop out a lot easier. Ive purchased 3 more. The price is great, and they are very durable as I've pulled on the ice to come out of the mold several times. It's super easy to use, and to clean. Ive seen some different ones that have 4 molds, but, the size I bought is perfect for both 30 and 40 Oz tumblers. For my husband's 30 Oz tumbler, I only fill the smallest mold up halfway way, so it is a bit shorter and then can fit all 3 in his cup. This is a great product!

It works! The ice lasted all day and then some. The mold takes up a lot of room but is worth it, easy to remove from the mold.Everyone has at least one of these mugs and to fill them up with ice cubes, takes a lot of ice. These are graduated so they fit the mug. Great Christmas gift idea.

Nice and sturdy. Works well enough. Takes some effort to get the ice out but running it under water works for me. Fits my 40oz cup perfectly

Saw this product on tik tok and came here to buy it straightaway. It’s the perfect size for my 40oz Stanley but would also work for other sizes. (Also works for off brand Stanley’s too 😉) such a cute mint color. Doesn’t leak because the lid seals well. Great quality especially for the price!

I love the idea of it it fits perfectly in your tumbler I just wish it was easier to get out

This is awesome for both Stanleys and Yetis as well as other off brand tumblers. Perfect for summer beach days your water will be ice cold all day!

I loved the idea of the ice maker for my Stanley cup. It does make perfect ice to fit in the cup. The problem is the ice is very difficult to get out of the mold. They tend to break while attempting to remove from the ice mold.

I don't have a Stanley Cup but I got these to freeze water for other water containers. I liked that the ice cube tray is easy to user. The ice pops out with little effort. Also cleanup is a breeze. I would buy again!
