The Duo Wall Glasses are a set of two innovative 450ml double-wall tumblers built for versatility. Made from mouth-blown, heat-resistant borosilicate glass, the double wall maintains beverage temperature while keeping the glass comfortable to hold.
A silicone vent at the base equalises air pressure between the layers to reduce condensation and heat transfer, and they are microwave and oven safe — presented in a printed branded gift box.
