This classical Cartridge bag is crafted from 18 oz. cotton canvas and trimmed with thick leather. The fabric is laminated with rubber to provide a robust water proofing and stitched with strong, oiled thread.
The leather is cut to our own pattern that gives the bottom of the bag a slight pendulum shape ensuring that the optimum quantity of cartridges (up to 100) are contained within a smaller bag and that they rest snugly together.  
The buckles are made of strong solid Brass.
A final neat touch is that the bag cover is not stitched to the back of the bag but hinged around a bar hidden within the back of the case. This means that the cover will rest neatly open and not flip to close.
