Exquisite 350ml double wall borosilicate glass coffee cup with a secure push-on polypropylene lid with silicone swivel closure and a wide heat-resistant silicone band. Borosilicate glass 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. The silicone flip closure can come in any colour from the standard colours at no extra cost. Up to five different colour combinations are included in the price and more are available for an additional charge. This product is not dishwasher safe and handwashing is recommended.
