These are a staple in my zero waste on-the-go kit... really they never leave my bag (except to clean them!). I use them when eating on the go, camping and lately out at restaurants (the chopsticks come particularly in handy at sushi restaurants that serve single-use sets). They've been through the dishwasher and were fine. When the bamboo get's a little dry, I plan to rub them down with some oil to rehydrate them. Oh, and I also keep my stainless steel straw in the pouch for the perfect on-the-go eating and drinking set!
