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