Elegant 350ml, double wall borosilicate glass bottle which maintains hot or cold drink temperatures for longer and remains comfortable to hold. It has a removable stainless steel infuser for tea or fruit and a secure screw on bamboo lid. The bottle is BPA-free and is manufactured from borosilicate glass which is incredibly light and very strong. Bamboo is a natural material which produces unavoidable variances in the grain pattern, colour, and branding. This product is not dishwasher safe, and handwashing is recommended.
