Ripple Thermal glass 22 cl, 2-pack by Ferm Living is made of mouth-blown glass and features the characteristic ribbed texture of the Ripple series. The double-walled construction helps maintain the drink’s temperature while the exterior feels comfortable to hold. The glasses are stackable for easy storage and are just as suitable for coffee and tea as for cold drinks. The set includes two glasses that work both for everyday use and for a more considered table setting.
