Durabilty: Made from borosilicate glass. Borosilicate glass is completely non-toxic and contains boron trioxide which allows for a very low thermal expansion. Meaning our glassware will not crack under extreme temperatures like regular glass, making our glassware dishwasher safe and safe for all your coffees, matchas, chais, cocktails and more!

Stackable: Each glass has a ridge on the bottom making them the perfect stack each time.

Handcrafted: Each glass is hand blown and handcrafted. Glass is handblown into our mould, while continuously rotating to distribute the glass evenly with the perfect composure of glass and air. Then each glass is placed to properly cool. Then a laser cuts all the ridges and then the base and top rim of the glass is sanded by hand.

Care: Dishwasher safe.
