Diameter in the menu is actually gauge and diameter

I have these in a few different diameter so pls chose from the menu. Diameters are always measured as inside diameters.
The ball size in 14, 12, 10, 8 and 6 gauge are both 6mm
The ball size in 4g is 8mm and 6mm
The ball size in 2g is 10mm and 6mm
The hoop is 12mm in diameter
These are externally threaded

Help with external threading:
If you run the threading through a bar of soap you will fill in the gaps for an easier insertion.
This is my creation. I am a piercer.
