Ice Cube Tray for Stanley Cup:Silicone Ice Cube Molds with Lid for 30oz 40oz Tumbler Cup, Ice Mold for Stanley Cup,Ice Drinks,Juice,Whiskey,Chilling Cocktails,Coffee,Tea, Car Gifts

I don’t have a Stanley but I have a cirkul 40oz tumbler with a straw. The new model. It’s instantly copy cat but made by cirkul. I’ve been seeing people on social media use these and I had to try it. It was SUPER HARD TO GET ICE OUT AT FIRST but I have sensitive fingers and I’m not that strong sometimes. But I found a way and they are the best. They fit perfect into all my non-Stanley 40oz tumblers just like they would in a Stanley. The rubber is great quality. Super durable for my crazy way of getting the ice out. The color is nice and its pretty self explanatory on how to use. Worth it!

Works great! The ice was a little tricky to get out at first, but it works exactly the way it should. I added fruits to mine and it definitely added some flavor. Very simple to clean. The color is exactly like the photo and worth every penny.

Good quality but hard to get ice out once frozen

It’s very difficult to get the ice out

I purchased this with the 30 oz Stanley not realizing that only two of the three would fit. With that said the ice that I did use fits perfectly and lasts a long time. Some difficulty getting the ice out of the mold at first but overall very happy with this product

These are awful. It is impossible to get the ice out. Like holy crap be prepared to spend 5 minutes removing the ice circles.

Really hard to get the ice out of. Lots of hot water and frustration later I finally had all three out.

This is a great item for use with the stanley tumbler
