Scuba Capsule

These are spy/survival capsules with a shape similar to a scuba oxygen tank. They are wider than other capsules being 2'' long with a 3/4'' diameter.

As other capsules this one can be used to store cash, pills, thread and other small items, they are very common for small items when geocaching; the wide body makes them useful for pills that won't fit other capsules and for other round items with a diameter as big as 3/4''.

They are made of aluminium with a rubber o-ring for sealing, so they will be water proof and dunkable. The capsule wall is quite thick so impacts and falls won't damage the capsule and its contents. They are slightly bulky for a keyring but that depends on personal preferences. They come with a split ring and a couple of extra o-rings, if you are going to take them underwater using two o-rings instead of one might be a good idea for extra safety.

If you think about using them as C123 battery holders please check some of the capsules fit a 123 battery and others don't due to minimal finishing details. One detail we liked is that since the capsule is opened near the bottom you can use almost all the volume of the capsule to store mini kits without anything dropping when you open it.

You can order them in red, blue or gun metal silver for $5 each from this website.
