Review on Artistic Wire Beadalon Professional Deluxe 5-Rod Coiling Gizmo: Versatile Wire Coiling Tool Set for Precision Jewelry Making, 7mm/5mm/3mm/2.5mm/1mm by 38.1cm by Jennifer Roberts

. The largest rod seems to give me a jump ring that is slightly larger than the 8mm jump rings I bought from the link below. Here is the cost analysis. In 20-foot spools, Artistic Wire Artistic Wire 18-GaugeTarnish Resistant Silver Wire, 20 feet costs 48 cents per foot. You can purchase the same Artistic Wire 18 gauge tarnish resistant silver wire 1/4 lb in a larger spool for 39 cents a foot. Rod Winders 7mm/5mm/3mm/2.5mm/1mm x 15" and each one uses about 1.1 inch of wire. So I get about 218 rings from this 20 foot roll at a price of $4.36 for 100 rings. Using the 1/4 pound roll mentioned above, I got about 534 rings at a cost of $3.69 for 100 rings. They're on sale now for $1.72. Sometimes when I order them I get different wire sizes, but I spoke to the seller and got what I wanted. So, in terms of cost, it is much more profitable to order them in advance.
