Exquisite set of two 310ml double wall glasses which are presented in a black gift box. They are manufactured from borosilicate glass which is incredibly light and very strong. The double wall construction keeps drinks hot for longer while the outside of the glass remains comfortable to hold and it keeps drinks cold without messy condensation. They are ideal for use as on-trend coffee cups or for serving icy cold beverages. Tivoli glasses are also great for frozen desserts which need to stay frozen for as long as possible. This product is not dishwasher safe and handwashing is recommended.
