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.

Perfect for our small, large glasses and water bottles. The ice rings last longer than regular ice. I will be getting one or two more.

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.

When using this it wouldn’t even freeze the first few times. Then when it did freeze it didn’t freeze into form. It froze all around and underneath. Stuck to the container. When taking them out they break. Not what I expected to be honest. I feel the design should be better. However it does fit well within the cup, the parts u was able to get in.

I purchased this for myself last year, and then for a friend and then bought two more this year for my daughter and daughter-in-law. You can use them in the 30 ounce or 40 ounce Stanley cups. The next day the ice is still there. No more filling the cup with ice and having trouble putting this straw in. Love it.

This item makes the most perfect ice cube cubes I’ve ever got to use. They fit in my 40 ounce Tumblr perfect. All three sizes come in handy. you can stick your straw in a cup without fighting bulky ice cubes.

buenos me sirvio para hacer hielos para los termos

I wasn’t sure what to expect, but I’m honestly impressed. These silicone ice molds make the perfect cylinder-shaped ice that fits right into my 40 oz Stanley tumbler. They keep my drinks cold for hours without watering them down too quickly. The lid is a nice touch—it prevents any weird freezer smells from getting into the ice, and the included bin keeps things organized. It did take a bit of practice to get the ice out easily, but once I figured out to twist gently and push from the bottom, it was super simple. Highly recommend if you're tired of small cubes melting too fast or don’t want to deal with giant chunks that don’t fit. I’ve been using it daily for my iced coffee and lemon water—love it!

Bought this for my 42 oz yeti rambler. All 3 ice cubes fit great, yes it’s a bit difficult to get out but that’s not really that big of a deal. Don’t have any weird film from use. Doesn’t take up a large amount of room in freezer. Would purchase again

La verdad estorba la caja en el congelador y solo caben los 3 cilindros de hielo en el Termo Stanley de 40 Oz en los menores no, pero el material es de calidad y cumple lo q dice el anuncio

This is a great idea and definitely fits the Stanley perfectly. It is a little tricky getting the ice out but overall great product
