I wanted a way to cover canned drinks in my shop to keep sawdust and bugs out, it snaps onto the top of the can securely and you can lift a full 16oz can by holding the lid only but I wouldn't suggest it. It also won't stop the drink from spilling. There are other uses, Ladies can use them to place a barrier between their drink and creepy men with ill intentions. For this reason make as many as you can and give/sell all you want or can.
