Rectangular Collins Ice Cube Mold with Lid - For Cocktail, Whiskey, Butter and More - BPA Free Silicone - 2 Trays - 4 Large Ice Cubes Per Tray

Just one of these keeps my 32 oz Hydro Flask nice and cold. And the "cubes" are easy to extract, as the silicone pulls over the end quite easily.One teeny tiny complaint. The outside edges tend to push in on the the 2 outside cubes, so they are never quite "full". And that "looseness" makes keeping the lid on a bit of a challenge as you move the filled mold from water to the freezer. Again, this is a microscopic complaint. I love using the bigger "cubes" vs. normal ice. It lasts much, much longer.

I bought 2 sets and use them in my instant pot to make breakfast tacos. The work perfectly. I dont have any issues with the egg sticking. I like that they come with a lid which makes for easy stacking. Easy clean up. I use them weekly and have not had any issues.

Perfect making homemade vegan butter. Love these things……

For those of you that are wanting to know it is bigger than a stick of butter...and its also flexible.

Great for the summer

Love it!

I bought these for the second time after having the original ones for a while. Within a few uses two of the trays have split leaving only three slots available on them. While they do as they need and freeze pillar ice they split very easily taking the ice out after two - three uses.This was not a issue with the ones I bought three or four years ago.

They would be great if it wasn’t for the fact they are way too flimsy . Put them on a cookie sheet or in a pan to put in the freezer, they have no sturdiness on there own.
