- What does 18 gauge mean here?
- The wire is 1.0mm thick, which is 18 gauge. That is a light wire, best for small charms and delicate chains rather than heavy pendants.
- Will these fit standard charm loops?
- The inner diameter is about 8mm, so they pass through most charm loops and small chain links with room to spare. Very fine loops may slide around inside them.
- Are they open or closed rings?
- They are open jump rings, cut through on one side. You twist them open with pliers, thread your parts on, then close the gap.
- Will the black finish come off?
- The black coating sits on the surface, so pliers can scuff it and repeated rubbing can wear it. Grip gently and touch up bare spots if the color matters.
- Do they rust?
- Iron can rust when exposed to moisture, sweat or humid storage. Keep finished pieces dry and store the rings in a sealed bag.
- Can I use them for heavy jewelry?
- Not for heavy pendants or pieces that take pulling. The 18 gauge wire bends under load; use thicker rings for weight-bearing links.
