The Humangear GoToob Bottle is the modern, smart, squeezable tube for traveling, outdoors, and more. Unlike typical hard plastic travel bottles, the award-winning and patented GoToob is easy to squeeze, and it dispenses the product right away. A special, "no-drip" valve helps the cap stay clean. The collar is made of two rings that unsnap from one another. The outer ring has an ID window, and the inner ring lists content indicators. Simply snap the outer ring off and back on to display "Soap," "Lotion," and more of your own contents. Slips easily into pockets, bags, purses, and other tight spots. The medium 2 fl. oz. size features a handy suction cup that can briefly attach to walls for moments when you need your hands free. Carry-on approved.".Capacity: S 1.25 fl. oz. / M 2 fl oz / L 3 fl oz.
