These tough machined aluminum capsules are made in a range of sizes to fit anything from mints to matches to money and more. Each has a screw-off top that seals to the body by compressing an O-ring, helping to protect the contents from getting wet or damaged.

Strong and rigid, they have a smooth, rounded shape to slip into a pocket or pouch without snagging, and they can easily be hung from a strap or belt loop using the attached split ring. The larger capsules (UC40 and UC50) can be used for anything from geocaching to holding a first-aid kit. Each includes a 1 1/2" (38mm) diameter split ring. The mini size (UC10) has a nylon lanyard for looping through buttonholes or around belts and backpack straps.
