Made from mule leather. This is a graceful, practical, durable hard leather flask. The pattern was taken from an original flask. It is wet molded by hand from 7-8 oz. mule leather and left in the natureal color. The stopper is hand turned from hardwood and fits snugly into the leather neck and secured with a small lace to securely contain your round ball or shot. This flask will dispense up to a .75 caliber roundball with ease. The new traditional design is an improved way to carry this exceptional flask. You can hang it from your shoulder with the long 72" shoe lace strap. Made in the USA by October Country, a manufacturer of muzzleloading supplies.
