The Built Planet bottle is a reusable bottle made entirely from recycled PET plastic, with each one made from approximately 15 plastic bottles sourced from school community projects. This leak-proof bottle is suitable for hot and cold drinks, and its matching lid doubles as a cup. The bottle is BPA-free and will not leak toxins or odours, even with hot or fizzy drinks. The Built green planet bottle is microwave safe and comes complete with a 12-month manufacturer's guarantee. It is lightweight and robust, fitting most car cup holders.
