3.0mm to 3.2mm
Been at 3mm for 3 months or so now, have had some 3.2mm jewelery for a while thinking id just be able to easily slip them in by now since its been 3 months... but nope!!
Tried yesterday and could not even get them started, so went back to the 3mm..
How the hell can 0.2mm diameter make that much difference!!π
