Handmade borosilicate glass tumblers, resistant to thermal shock. In Quattro stagioni we find dotted the alternation of colors in the succession of the various moments of the year: from ice white and blue of winter to green and red of spring, from amber and orange yellow of summer to red-brown dotted with touches of a light green of the autumn. This collection is made of borosilicate glass, handmade. Each package includes the four colors. Design Federico de Majo 2019.
