. 16.5 ( h ) cm . Borosilicate glass, wheat straw & cork 480ml Packaged in a colour box A reusable alternative to disposable coffee cups. The cup is made from tough and strong borosilicate glass. The band is made from elasticated cork to insulate the hand from the heat of the beverage inside. The lid is made from plastic mixed with wheat straw. Wheat straw is the stalk left over after wheat grains are harvested. Traditionally it has been treated as waste, but now it can be used in combination with traditional plastic. This reduces the quantity of plastic needed to produce an item, and accelerates its biodegradability once it is eventually disposed of. Use & Care Wash before first use The glass cup is dishwasher safe, but it’s recommended to hand wash the lid so as not to damage the seal. The sleeve should be removed before washing the cup in the dishwasher. The glass cup is microwave safe but the lid and band are not. Caution Use with care when consuming hot beverages Do not overfill Ensure lid is secure before drinking Do not hold glass filled with hot liquid without the cork sleeve Do not use glassware that is chipped or cracked
