This is a new clever idea of turning any concho into a button for decorative or practical use. Simply screw the adapter assembly into the concho and you have a loop ready for sewing. There are several other leather craft kits, stamps, tools, dyes and laces also available in our stecksstore. If you are interested in additional quantities or other items, please feel free to contact us.
