This BB Container in particular holds about 25 BBs. The amount held can be more or less depending on the length and/or width of the pen. The BBs shown are the .177 kind. With that in mind some of the bigger BBs may not fit with standard pens.
These could be held in your pocket when you have a BB rifle/pistol that does not have a built in magezine like the Crosman 1337 American Classic.
These could also be used if you have BB gun "wars", acting as "supply stations" or carry-on ammo.
