Physis
Physis - The system of adherence changes the way of perceiving the glass, no longer as a single block, but as a dialogue of elements. This system makes easier the washing operations (the two parts of the glass are better to dispose in the dishwasher), and it decreases a lot the space needed to store the glasses (you can stack the two parts).
Moreover Physis is not a simple cocktail glass: you can use it normally or upsidedown, if you need a long drink glass.
It is a dynamic glass, sustenibility oriented.
