Penta-off / bottle cap


Taking a drink is easy, but getting the cap off often is not.

The problem comes from not being able to find a point of exertion on a round cap.
Especially when your palm is sweating from fighting the bottle.Twist the mind a bit,
and the Penta-off is born!

With this pentagon cap, twisting the cap off is easy to find a point of exertion .
Drinking up, of course, is never a problem.
