Blue-green, hand-blown tumbler with a beautiful tulip-like design. The glass belongs to the London-based design studio Campbell-Rey's Cosimo collection. It is made in Murano, but unique in that it is blown in Pyrex glass instead of classic Murano glass. Cosimo combines traditional Venetian glassmaking with all the practical attributes of Pyrex, with enhanced durability and heat resistance. Consequently, the pieces can be gently washed in a dishwasher.
