I use the orange cases like you find at wal-Mart. Never had a problem with them. My first one is almost 30 years old and still serves as a mini kit. Recently I bought one by Coleman and was pleasantly suprised to find that it came with waterproof matches and a sizable striker strip inside a tiny zip-lock. I rut the matches in the zip-lock and tossed them in general gear for "just in case". Have any of you tried the brass Siva case with a compass on it? I have been considering it, but no one has one to examine. Thanks
