Review (1/5): DON'T BOTHER!
Do. Not. Purchase! They arrived in a vacuum sealed package. I hoped they would regain their shape after removing them from the plastic. The only memory this foam has is being crammed into a plastic bag and suffocated. After 3 hours they still look like mangled twist ties. Ever wrinkle in the plastic bag is now permanently etched into their shape. I'm throwing entire bag away and ordering some silicone ones.
