WUJUNIce 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)

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!

Great for really hot days. Mine has stayed frozen over night. Only thing l found difficult was getting ice out of moulds. The box you place the moulds in is great idea.

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 cold for over 24hours. Easy to fill, easy to remove. Takes up a bit of space in the freezer but as it’s in a box you can stack it on top of things and also put things on the top of the box. I have an imitation Stanley 20oz and these ice rings fit perfectly.

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.

Excellent item I love it, helps keep drinks even cooler

Love these. The tray and lid makes it so much easier to place it in the freezer much spillage. Easy to take out the blocks too. Can't fault it.
