Ice Mold for Stanley Cup, 4 in1 Silicone Hollow Cylinder Ice Cube Tray Compatible with 20-30-40 Oz Tumbler, Drink, Juice, Whiskey, Cocktail.(Green)

I like how the ice keeps longer but its a pain to push out the shape after freezing. Also, if you plan on using this custom shaped ice, you'll need more than one mold as I wud go through more than one ice shape per day. Overall, this is a great Idea - but kinda pricey!!! As with any custom ice tray shapes, you pay for the shape

Used it with my 30oz Stanley tumbler and I can fit all four pieces in, definitely works with 40 oz too. Great quality and definitely worth its value!

Durable and good quality.! cute!! Easy to use. Great for space saving. Fits well with my cup, very happy with this purchase . Came exactly as described.

This is ok. Hard to get ice out but it is cool to have fitting ice cubes.

Got this for my Stanley mug. One of my biggest complaints is that the ice doesn't last as long as it should. The ice cube form is made from silicon and the size is perfect for the mug or similar size and shape cups.It's super easy to use. The form came in a nice and cute box. Open it up snd washed it. I didn't follow the instruction on boiling the water before pouring it into the form. I just use my filter water and fill it to the top and place the lid on it and place it in the freezer.The form doesn't leak and the shape is perfect for my mug. No complaints and it works as advertised. Now the ice will last long since it's one big circular form. More room for your drinks and less ice that takes up room.Great product and will get another set for the wife.

These molds work great! The ice lasts all day and quickly cools any water you add. It takes a bit of effort to pop the ice out, but it’s not much of an issue. Just make sure to place the ice in your cup before adding water to avoid the cubes floating and making a mess.

This item is so great with Stanley's or 40oz cups. Makes a big difference. Color is nice. Ice freezes fast.

Ice last all day
