This is a Hong Kong 1 dollar Elizabeth II coin converted into a concho. I have modified a circulating coin into a concho. The screw size is M4. The length is approximately 5mm. An 8mm screw (longer) is also included. Please use it on thick leather. Compatible with large jumper snaps. The photos are from a previous listing. The item shipped will be of the same quality. Shipping will be via Yu-Packet Post Mini. Thank you. If you need multiple pieces, please check the stock beforehand. Shipping costs will be discounted for the second item onwards. I will relist them as a multiple-piece set. #Leathercraft Material
