Humangear Made from soft yet rugged silicone, so it's easy to squeeze and dispense the contents. A special, "no-drip" valve helps the cap stay clean. A window in the collar identifies popular contents. Rotate the window to "Soap", "Lotion" and more - tighten the cap to lock in the setting. A large opening makes it easy to fill and clean. Large 3 oz. size gives you maximum volume for longer times between refills. GoToob is approved for airplane carry-on, it's food-safe (FDA), and 100% BPA-free. Recommended for shampoos, conditioners, lotions, suntan oil, liquid soaps, condiments (ketchup, cooking oil, etc.), hand-sanitizer, body wash and many other low and medium viscosity fluids. Measures: 4.5 x 1.69 in. (43 x 115 mm).
