Decoration pistols and band guns can be carried, by "just sticking them into your belt" or by storing them in a holster.
The clever variation is to buy a holster for each single gun and to decorate it as you wish. Plus: the gun will not interfere with your movement and stay right where it should.
The holster is made from two pieces of durable upper leather and riveted along the edge.
The "side" information refers to the side the holster is being carried on on the hip.
The opening on the bottom allows the barrel to stick through a little.
