WUJUN Ice Cube Tray for Stanley Cup 30-40Oz Tumbler, Silicone Ice Cube Moulds with Lid and Bin for Chilling Cocktails, Whiskey, Drinks, Coffee, Easy Fill and Release Ice Make (Green, 40 oz)

This was actually bigger than I imagined. Happy with the buy

If you have a stanley shaped cup, you'll need these to keep it cool all day long, easy to fill easy to remove ice cylinder, although I've cracked a few. Doesn't take up much space in freezer. Will still have ice in by end of day and nice and cold to drink. Have the 30oz stanley size and use all 3 ice cylinders. Very happy with ice tray.

Easy to use but ice doesn't last as long as it should. Worth buying to keep cool

Definitely purchase this product if you have a Stanley cup! Ice lasts all day from about 8am until 9pm.I don’t like room temperature water so this helps me to get through 3 refills a day when in the office.So easy to use and ice comes out easily for use.

Perfect for Stanley’s! So good I got another for summer/hot days, so I can use one and still have one frozen ready to go!

Price when reviewed: £ 13.99.This kit comprises a lidded box and a silicon ice mould in a shade of orange that creates 3 ring shaped pieces of ice that fit inside a 40oz drink tumbler. Cleaning is easy, especially if you have a dishwasher.Put the mould into the box before filling with water as the silicon is very flexible. After filling and putting on the box lid it will take approx. 4+ hours for the water to freeze. I filled the moulds to the top which was a mistake as water expands as it freezes, so my first attempt came with slightly misshaped ice cylinders as can be seen in the photo.Taking the ice out of the mould involved peeling the silicon back and pressing the middles through the ice cylinders. The water stayed very cold for more than 8 hours, but that could be the double walled drink tumbler I was using. If that’s not long enough, you could always fill up the centre of the cylinders with ice cubes.The box is quite large and does take up a lot of space in my freezer as it needs to go into one of the drawers, whereas I do have a separate tray section for ice cube trays, Whilst this is a nice idea, you’ll only be able to use the largest ice cylinder if you have a drink tumbler large enough to accept it and room in your freezer to make them. I haven’t been able to clip the lid on the box it just lays on the top.It does produce unique cylindrical ice, but regular ice cubes may be an easier option.

Absolutely brilliant item. It arrived the n CT day. I bought it for my 1.2L Stanley cup and it's perfect.

Kept my water so cold for so long only issue is the largest ice ring is a little too big and needed a bit of water to melt a little
