These aluminum silo shape capsules are great for keeping things dry that need to stay dry. Stuff pills, money, tinder, or anything else inside. The screw off part is the bottom instead of the top like our other capsules. There is an o-ring to make it watertight, and a split ring so you can attach it to your keychain, pack, or anywhere else.
Please note that the pictured battery is not included and is just for size reference.
