Product Description
My jump rings are made completely by me - hand coiled wire on hardened steel mandrels, then precision cut for perfectly flush cut rings. Tumbled with stainless steel shot to clean, harden and bring them to a beautiful shine makes them perfect for making chainmaille or to use however you like in your own handmade jewelry.

* The "actual" measurements on the large diameter sizes above were made after closing the ring with my pliers, tight and flush without any gaps. The bigger the diameter of the ring, the more the coil of wire can "spring back" from the mandrel which it's coiled on, causing the ring, and thus the ID and OD to be larger than the mandrel size. Please note that I still label the rings by the size of the mandrel they were coiled on (or it would be too confusing!)
Inner diameter is the diameter of the mandrel, or steel rod that I coil the wire onto before cutting into rings. Some springback will occur, making the inner diameter of the ring slightly larger than the mandrel diameter.

20G Jump Rings
Posted by Nancy D MacIver-Neeb on 24th Oct 2018
I buy these in bulk as I use so many. I could get them other places but the consistency in the cut, the even edges, and the shine provides rings that are easy to use and don't need additional finishing once I have them in my pieces. I make sure I have these on hand at all times!

Customer since 2012
Posted by Malina Bowen on 23rd May 2014
I have been a customer since April 2012 and have never ever been disappointed in the products or the service I've received. Shipping has always been extremely fast and no mistakes have ever been made with any of my orders. She's always so helpful and honest, so I don't hesitate to ask for assistance. These jump rings fit so well together that you have to look at them up close to even see the saw cut once they've been closed. I use these rings in creating my wire wrapped pendants and I've sold over 3000 pieces with her rings as a component. Not once have I ever had a customer complaint about the rings breaking or pulling apart.
