B / Reusable Boba Tea Cup


B condenses the plastic components of a bubble tea cup redesigned into a single reusable cup, retaining the drinking experience through a recyclable silicone tip (free of BPA, BPS and other carcinogens) that provides the same suction as a straw. A simple twist of the lid allows access to the topping holder, allowing you to swap between your favorite toppings or drinking tea. The lid is made of wheat straw plastic which utilizes agricultural wheat residue. HDPE is used for the cup for its durability, high resistance to heat and non-toxic chemicals.​​​​​​​
