Made of stainless steel with a non-slip PVC handle, this mandrel will give you consistent size loops time after time. This tool offers five different diameters of 1.5, 2.5, 3.5, 4.5 and 5mm for whatever sized loop you need. Use it for making loops in wire work, or coil wire around the mandrel and cut to make your own jump rings. Nicely rounded and extremely smooth so wire will not be scratched.
