Borosilicate glass glass
RIEN is a drinking glass, simultaneously delicate and stackable. The perfect glass for a drink at the bar, a wine or just some water. A cone-shaped, curved base gives RIEN not only its unique form, but also additional functionality: when the base is full, it measures exactly 4 cl. Its robustness and heat resistance originates from its material’s properties: produced from borosilicate glass originally used in scientific research.
