Not sure who made it Izzy. The guy at the show had a box of leftover supplies from a scout troop making kits. Got a firesteel, a little razor knife, a tiny saw amd a button compass I wouldn't risk her life on. There's no clamping device to keep it closed, just some tiny bumps to hook under the rim of the lid. I never trust anything that says waterproof unless I test thoroughly. Thats whu I had considered the plastic one with a rubber seal.
