This just showed up the other day -- wanted something a little bigger (and sturdier) than an Altoids tin for putting together a small pocket survival kit. The container is Type III hard anodized aluminum, and while it looks heavy, it's actually very lightweight. So far, it seems to be working out well. Stuffed some survival and EDC goodies inside, and replaced the ferro rod in these pics with a Spark-Lite. Overall, it's not something you are likely to carry in a pair of jeans, but it definitely fits in cargo pants/shorts or a jacket pocket.
