Made from a special, extremely durable nylon. Dishwasher safe (top rack only) - FDA food-safe - 100% BPA-, PC-and phthalate-free. The utensil set for people who want a real fork and a real spoon on the go Utensils are each long enough to be used separately and both are optimized for what they need to do Tools snap together in an ultra-compact nested mode. They can also be re-connected end-to-end for eating out of rehydrated food bags, deep to-go containers, etc. Locking mechanism has been carefully designed for easy cleaning even when you're miles from the nearest dishwasher GoBites took over two years to develop, but we think they were worth the wait. We wanted to create eating tools that many different types of people can use in many different situations, and we wanted to make them simple, extremely durable, and a joy to use. We're confident that we've achieved all of that and more with GoBites. Duo is a decidedly clever two-piece fork and spoon set. A unique interlock mechanism allows the tools to nest in an extremely compact form for transport and storage.
