New, Unused Item OLD MOUNTAIN VINTAGE BLACK SIERRA Pattern Old Mountain Vintage Black Sierra Cup Pattern Based on the Old Sierra, which faithfully reproduces the thick vintage Sierra of the time, the surface is damaged and then black oxidized to give it a rugged and cool look as if it has been used for a long time. It also has the characteristic of being more resistant to rust than stainless steel because the oxide film becomes thicker. Due to the nature of the processing, each item has unevenness and a different finish. The appearance will change depending on the frequency of use and the aging process due to friction. asimocrafts Asimocrafts Asimocraft nerudesignworks Nerudesignworks oldmountain Old Mountain molds Molds thearth Thearth Makio Trunk Zero Trunk Zero sanzokoumuten 3zokoumuten Sanzo Koumuten rodan Rodan deviseworks Deviceworks 38explore 38 Explorer somabito Somabito ballistics Ballistics gripswany Gripswany
