Multi purpose, so use it however you want.
One main compartment, measuring around 13 x 19 x 4 cm, with a zipper opening. Front compartment has a velcro flap on top, and a buckle in front for further security (or better looking). There is also a minor compartment on that flap, sealed by a zipper.
Same thing again:
made of heavy duty, abrasion and water resistance 1000 denier Invista Cordura nylon fabric
military specification nylon webbing, light weight, abrasion and low temperature resistance
most durable YKK zippers, heavy duty guarantee
ITW Nexus & UTX buckles adopted to comply military specification
and in the latest A-TACS camo again. Nice for airsoft, but even if you are not an airsofter you can simply buy one and wear on your belt for daily casual occasions.
