Each year, 100 billion single use coffee cups end up as landfill. Thats why we created Ecoffee Cup, an environmentally responsible reusable made with naturally organic bamboo fibre. Its BPA & phthalate free & at just 135g, its light, sturdy & best of all, biodegradable when youre finished with it. Its also dishwasher safe & has a fully sealable non-drip lid. Thats why Ecoffee Cup is the Natural Reusable. Not suitable for microwave.
