We were the first to recognize the need for a tool that allows the relatively small user to easily manufacture perfect jump rings in a variety of diameters and wire sizes. The tool had to be easily operated by anyone and be affordable. The result was the Jump Ringer. It has been copied by others but, because we are constantly improving it, Jump Ringer remains the most efficient and, in the long run, the least costly system to operate. We offer free unlimited expert telephone technical support to any owner or prospective owner.
