This fantastic coffee cup is great for the environment, helping coffee shops cut down on their single use polystyrene cups which are non-biodegradable. They are also dishwasher safe! Our reusable coffee cups are made entirely from organic bamboo fibre which is easily biodegradable. The silicon which protects your hands from the heat, whilst not being biodegradable, is widely recyclable. When you use one of our cups you can rest assured that you are helping prevent further damage to the planet. They are also free of Bisphenol-A (BPA).
