The X-Mug is constructed from a flexible food grade silicone. A rigid ring within the rim keeps it sturdy to hold onto and easy to drink out of. The mug collapses to a disk that fits in the palm of your hand. The X Mug fits neatly into the X Bowl and X Plate and altogether the collapsed set is less than an inch thick.
