Reusable travel bottles and travel tubes are safe, soft yet rugged so it's easy to squeeze out all of the contents - great for sauce, baby food, salad dressing. Alternatively they are a clever way to pack shampoo, moisturiser and creams when travelling outdoors and the Humangear GoToobs are a handy size for flying for work or a holiday (please check quantity limits with your airline). All of our travel tubes are BPA free, PVC free.
