This is a German 5 Mark concho from before the EU. I have modified a circulating coin into a concho. The screw size is M4, with a length of approximately 5mm. An 8mm screw for thick leather is also included. Compatible with large jumper snaps. The photos are from a previous item; the product shipped will be of similar quality. For multiple purchases, the shipping cost will be discounted from the second item onwards. Thank you. #Leathercraft Material
