This lovely Biodegradable Eco Rice Husk Reusable Coffee Mug is non-toxic and BPA free, and it's made of a fully biodegradable rice husk fibre material. It's super easy to clean and it's really durable. It comes with a snap on/off lid with a nifty little stirrer which goes in the lid hole; it also comes with an insulated band to protect your hand when you've got your hot drink inside. It's dishwasher, freezer and microwave safe to boot.
