Good heavy quality leather. Holds my colt pistol flask firmly. Brass closure is easy to use, not a snap, so it doesnt put pressure on flask when closing. Nice Product.
I bought this to assist me on the firing line with my blackpowder pistols. I also bough the Walker flask for the same use. The Walker flask will fit in the pocket. You may need to remove the snap for a leather thong to go around the neck of the Walker flask, but that is the only modification. I am pleased with the purchase and the delivery time.
