Tcamp Ice Mold for 30-40 oz Tumbler Cup, Silicone Ice Cube Tray With Lid and Bin for Freezer, Ice Ring Ice Maker for Chilling Cocktails, Whiskey, Drinks, Coffee, Easy Fill and Release (Black)

The Tcamp Tumbler Ice Mold is a fantastic way to keep my drinks cold for hours. The hollow cylinder shape fits perfectly in my 30–40 oz tumbler cups, and the silicone molds are super easy to use and clean. I love that it comes with lids and a bin for the freezer—makes storage neat and hassle-free. It’s a simple but clever solution that works great and adds a fun touch to my beverages. Highly recommend for anyone who wants long-lasting ice without the mess!

Work great. Fit my 30 oz Stanley with my straw lid. A little hard to get the ice out but I’m happy with my purchase

I purchased this for my 40oz Stanley. It fell short of the height to fill the cup near the brim looking as though it could accommodate one more largering of ice (I subsequently ordered the four ice rings mold). I did like how easy it was to remove the ice rings from the mold after letting it sit for five minutes in a room at an ambient temperature of 70°F, with the assistance of the pulls affixed on the underside to facilitate inverting the mold. I'd say returning the mold to its original position for making ice was more difficult than the ice removal, and even that wasn't that daunting. As for the ice's longevity in the cup, regular ice cubes have lasted longer. My guess for this phenomenon is the walls of the rings aren't as thick as the ice cubes, and the cubes disperse the cold more efficiently throughout the liquid due to increased surface area of the cubes. The box and cover does lend rigidity and protection when stowing the mold in the freezer to make ice, but I think it also buffers the mold from the cold, to the degree that it takes significantly longer to freeze solid. If you just rest the lid on the mold, and not use the lower box portion, it will freeze faster as air can circulate around the mold while protecting the taste of the ice.

Cute color, the holder is good quality, the ice try its self is good also. Only issue is getting the ice cubes out due to the cold but that's because its ice! Lol recommendation don't fill them to the top of the center allow some room for movement. Would recommend! I have a 30 oz stanley

these are really hard to take out of the mold and when you’re done you have to put it back together but it does fit in the Stanley perfectly and it’s really nice when you use it

Used this for a Brumate. The fit was perfect. The liquid will stay cold more than 24 hours. Easy to use. Does not take a lot of room in the freezer. High quality.

Works like a charm. Fits perfect, can use 2 at a time in the 30oz mug. The carrier case doesn't stay close. No biggie, you just keep it on the shelf anyway

Works well, little difficult to get the ice out of the molds
