layered glass by keiko okamoto from japan

It looks a wine glass at one glance, but it consists of 2 pieces; a cocktail glass and a tumbler.

A pair of glasses is always set in one. A tumbler is layered on a cocktail glass. It is a rotatable wine glass when they are layered each other. They are used side by side when they are on use. When you use one of the glasses, you may need a drinker for another glass. This separatable wine glass could bring you someone who drinks with you.
