A waterproof plastic container about the length of your forefinger with an application brush right in the cap. These are new and clean, so you can also use them to store small items, such as matches, needles, etc.

This care can is a part of the SSG550 cleaning kit. This rather cute little thing will work on its intended application (= greasing things up), as the little brush easily reaches crevices and corners otherwise hard to get at. Genial. But if the can itself tickles your fancy, not so much the brush, you can cut it off and what do you know, you have a waterproof matchbox.

Because the can is Swiss made, it's surprisingly pleasant to use thanks to the well sliding threads, overly heavy duty rubber gasket and "ribbed for her pleasure" general look.

Swiss army surplus

Unissued Swiss army gear. They really make even small things like this extremely well, it's almost weird how pleasant this thing is to use. Get a couple of these immediately, you will not find a better one for this price.
