This unisex shoulder bag was the original idea to create a bag from a single piece of leather, from which has several variations of differing sizes and shapes have evolved. It was conceived from a desire to create a bag from a single piece. (Although an unrelated Google search revealed that a similar concept is already used by the Serbian army as ammunition cases, hence the “Ammo” reference). The simple cut and fold construction allows for a self-supporting and robust bag which has just two side seams and a fully integrated flap. It has a zip pocket on the outside front section, protected by the flap when fastened and a roomy inner pocket to the rear of the inside of the bag. It comes on a leather strap with a medium sized buckle for fastening and a matching buckle on the shoulder strap.
