Silver plated pewter crimp-on cord ends. Fits 2mm cords. Simply insert the cord into the end of the finding and secure it in place by crimping the center section of the finding with a pair of chainnose pliers.
Sold by the pair.
Made in China
These look very sturdy and would hold tightly. They are very small, though, and would probably fit only one or two c-lon cords. I didn't see any larger offered on the website. Hope to see some in the future!
