Good to have just in case
These are so cute. I had no idea what to do with these, so I filled them with water and stuck them in the freezer, oops. Lesson learned, they are still in good shape after that mistake.<br />They feel like a quality material. They had that plastic or rubber smell to them. The opening will easily fit ice cubes (which is what you are supposed to do). The cap fits on nicely and I don't see any leaking.
