Nordic Ice Nordic Ice NOR1040 No-Sweat Reusable Long-Lasting Gel Packs, 24 oz. (Pack of 3)

size of each pack?

Does this product freeze solid?

how long can they keep a cooler cold, say in 80-90 degree weather?

How is the 16 oz pack bigger than the 24 oz pack? Are the product dimensions switched between the two products? I'm confused.
