The original, award-winning and patented GoToob! Made from soft yet rugged silicone, it's easy to squeeze, and it dispenses the product right away. A special, "no-drip" valve helps the cap stay clean. The small 1.25 fl. oz. size slips easily into pockets, bags, purses, and other tight spots. The medium 2 fl. oz. size is the only size to feature a handy suction cup that can briefly attach to walls for moments when you need your hands free. All GoToobs are approved for airline carry-on, they're food-safe (FDA), and they're 100% BPA-free and PC-free. They are also covered by our lifetime warranty.
