It is a very desirable piece of kit, but I made somwthing very similar (and much more visible!) from a plastic "pritt-stick" childrens glue stick.
The Brand name, product info etc is on a cellophane sleve that comes off easily, I waterproofed the opening at the bottom with a liberal application of epoxy, stuck match-striker onto inside of screw-on lid & stuff the capsule with matches, button compass, flint rod, scalpel, vial of fishing gear, vaseline/cotton balls, puritabs, "magic" birthday candle & miniature chem-lightstick. I carry it on a beaded-chain attached to the loops of a plastic-sleeved SAS wire-saw (idea plagiarised from Ranger Rick), & find it works pretty well.
