I currently wear a 0 gauge / 8mm Prince Albert and would like to stretch to a 00g / 10mm. I have found every stretch so far relatively easy because there has been a 1mm increase with each gauge. The problem is that there is a 2 mm difference between a 0g and 00g! I have all the streching tapers and I have tried to stretch up twice unsuccessfully. It just won't go! I have tired to get a 9mm (0.5g) ring but have only found 2 suppliers. One site is charging only £6 ($12) but they are out of stock. The other site is charging £48!! Way too expensive. Can anybody help me out on this one?
