ULINE Cold Bricks maintain their shape, even when they aren't cold. They don't become floppy and droopy when warm the way the ULINE Cold Packs do.
I received these 20 Cold Bricks in a big package of perishable specialty food that I ordered from a company halfway across the country. They really do work. My food arrived cold on my doorstep, even though they were in transit for about 18 hours.
