The X-Mug is constructed from a flexible, European standard compliant, food grade silicone. Double the size of the X-Cup, the X-Mug can hold plenty to drink. The rigid ring within the rim keeps it sturdy and easy to drink out of but still allows the cup to be collapsed into a flat disk that will fit almost anywhere.

• Volume is 480ml (US 2 cups)
• BPA-free, food-grade flexible silicone sides
