Copper Jump Rings Medium 16g Jewelry Supplies JSJ106 Jewelry Making & Jewelry Repair 6.5mm 10-Pack


These sturdy jump rings are made from round 1.2mm thick copper wire. They are made by winding copper wire around a five-thirty-seconds-inch mandrel, then cutting the coil down the middle. They have an inside diameter of approximately 4mm. When finished, the outside diameter of the ring is about 6.5mm.

These small, copper finishing rings have a tight aspect ratio which makes them quite strong for their size. They make an excellent choice for light to medium earrings, chains, and other copper projects and accessories.

Each package contains ten rings. All of our finishing rings are made from pure, solid, raw, red copper.
