The award-winning GoToob is made from soft yet rugged silicone, so it's easy to squeeze and dispense the product. A 'no-drip' valve helps the cap stay clean while a large opening means it's easy to fill and clean your GoToob. A window in the collar identifies popular contents; rotate the window to 'Soap', 'Lotion' and more, then tighten the cap to lock it in. The medium 60ml size features a handy suction cup that can briefly attach to walls for moments when you need your hands free. Pack contains one green, one clear and one blue coloured tube. All GoToobs are approved for airplane carry-on, they're food-safe (US FDA) and are 100% BPA-free and PC-free. They are also covered by a Humangear lifetime warranty.
