Bento hide is acquired by killing a bento buck. When killed, the buck's torso is the hide, like when you kill a deer, but it's brown. You can use this to craft into bento leather, which can be used in quivers and armors. Bento hide itself is relatively useful to many new tribes, as it's easily traded to tribes who don't live on or near the islands that bento bucks live on, making it a semi-valuable trade item. Bento hide is a slightly lighter shade of brown than bento leather, making it difficult to distinguish between bento leather and the hide.
