Clever Tubularis / Straw

Clever Tubularis

The drinking straw differs from the traditional one because it is thick at the top and thin at the bottom. It has the advantage of breaking the silver paper thoroughly, leaving a tiny gap between the straw and the package, which can balance the inner and outer pressure and avoids the ejection of drinks.
