The compact X-Cup is perfect for smaller hands or just smaller amounts. It is constructed from a flexible, European standard compliant, food grade silicone. A 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.
