The design disappears: only a shape with perfect geometries remains. A unique element, in which Marco Sironi confirms a functional and pure trait. The entire collection is made of borosilicate glass with very thin thickness, the result of a new processing technique of lampworked glass, all handmade. This collection is characterized by the purity of the lines and the very thin bottom of the glass. Everything is so thin that the glass almost disappears when water is poured. The content gives the form, not the container.The collection expands thanks to the new sizes of the tumbler glass and the addition of a long drink tumbler.
