RJF Leather was started by Roger Folmar in 2004. Roger retired after 40 Years in the leather industry. The tradition of fine quality leathers for belts and holsters is carried on at Keystone Leather. Keystone Leather and RJF Leather operate out of our Williamsport, Pennsylvania factory. The owners of Keystone Leather have over 80 years of experience in the tanning and leather industry. We proudly manufacture products for the footwear, belt, holster and small leather goods industries. Walk-in customers are welcome.
