I'm always on the lookout for new ways to "package" portions of my kit, and I picked up one of the Silva matchboxes last weekend. I'm pretty impressed. It has a threaded top (unlike similar ones that rely on o-ring friction) with an o-ring seal, and a reasonable backup compass. It fits nicely in the outer pocket of the SOE sheath on my Buck-Strider Solution. I filled it with matches, a spark-lite, and some wire, and there was still a bit of room to pad with tinder.
Interesting and low cost (about $11) waterproof gadget!
