5 PCS Large Ice Cube Tray,Large Ice Cube Moulds for Ice Bath, Easy Release Reusable Giant Trays Making 4.5 lbs Ice Cubes for Ice Bath Cold Plunge Tub or Coolers

these are great - I use them to make ice blocks for my coolbox for camping trips. They come with a coating of white powder (I assume some sort of lubricant powder) - but that's easily washed off, and not really a problem as you aren't likely to use these in direct contact with food. They keep their shape when they have water in them, which is great, and once the water is mostly friozen, you can stack unfrozen ones on top (careful with this though, I did this too soon and got water everywhere - my fault). They are light and durable and pack nice and small, so if you're camping like me, you can take them with you and freeze more water at the campsite if needed. Easy to use, no leaks, great value.

Great ice moulds keeps the temperature stable in ice bath due to the bigger size.

Work really well and create large ice cubes. The only drawback is that because they don't have lids they can't be stacked in the freezer which makes it hard to get enough of them in the freezer at the same time

Yup, they work! Nothing negative to say about them. Very happy with the purchase.

Excellent product good value for money.

Absolutely great, my son loved it. He’s 6ft 3” and the size is perfect for him.

Good price and good quality

Not stackable in the freezer. Very wobbly/ flimsy - better off with Tupperware with lids
