Borosilicate glass tumbler with a silicone protective sleeve and a bamboo lid and straw. Capacity 450ml. Enjoy a healthy lifestyle and stay hydrated throughout the day. This tumbler helps you with that and it looks stylish and natural thanks to the bamboo elements. As it is made from borosilicate glass, it can hold both cold and hot liquids, so it's perfect for bringing coffee, tea or other warm drinks with you. As this is a single wall mug, heat transfer can still occur. The silicone protective sleeve will make it easier to hold the tumbler when a hot liquid is inside. Bamboo is a natural product, there may be slight variations in colour and size per item, which can affect the final decoration outcome. Size: Ø6 x 20cm
