I have this case that I call my Yellican case that I bought to keep a gun and some ammo in so I could grab it and go and have everything in one place. After a while I realized that Pelican cases are overkill storage for something as tough and waterproof as a Glock so the gun went into something much lighter and softer and I have an empty expensive dry box just begging for some cool and useful contents. The stainless shackles are for a paracord cobra stitch shoulder strap that I took off. My first thought was a first aid kit but I have a nice one with all I'll need in a small 1020 case and a big one in it's own Pelican-like dry case. I don't have any expensive electronics that need that kind of protection and everything else I have is either tough enough to stand on it's own or living in another EDC pack or BOB of some sort. I'm looking for that thing I haven't thought of yet, some kind of kit I can put together in this case that I may not have realized I need or wanted yet.
