Made of stainless steel with a non-slip PVC handle, these 6" mandrels will give the user consistently sized loops time after time.
The smaller mandrel has steps measuring 1.5mm, 2.5mm, 3.5mm, 4.5mm and 5mm.
The larger mandrel has steps measuring 6mm, 7mm, 8mm, 9mm, and 10mm.
These mandrels are nicely rounded and extremely smooth, so wire will not be scratched.
If you don't own it, you should. What a time and money saver. Your jump rings will be perfect everytime.
I wish I had had this tool 20 years when I started doing jewelry repair.
