Handmade out of upcycled wood, all Peterman's products are food safe. These round hand turned bowls must be hand washed only. Their Gray Driftwood Round Bowls are made from upcycled Oak logs. Each piece is carved out on a lathe, ebonized, and rubbed with a food grade milk paint finish and seale(no conditioner needed). These bowls are a perfect fit in a seaside home or a subtle modern statement in an urban apartment. Of course, as always, they are great for salads!
