Our waterproof Aluminum Storage Capsules are ideal for storing useful items that contain small parts, and need to be kept dry. Medication? Matches? DIY Kits? You'll be able to organize and protect essentials like this in these useful storage containers. Better, we've included a small carabiner, so the storage cylinders can be attached to belts, backpacks, purses and more. This set comes with a medium, large and x-large capsule bundled together as a 3-pack.
