The more we design and string, the more we need jump rings…including soldered ones. The beauty of a securely soldered ring is you can stop worrying about it “jumping” off your design. It’s closed for good! Project Ideas: Soldered rings are easily the star of the show in projects like our Goddess Bracelets, or any project where you need a closed ring that won’t budge! Inner Diameter: 5.9mm Outer Diameter: 8mm Gauge: 18g Made of lead-free hypoallergenic brass, plating can contain up to 8% nickel. Made in Korea. Sold in packages of approximately 50 rings.
