Chastity and orgasm denial discussion

Hi A little while back I stumbled upon a site offering locking piercing rings. What set them apart was their perfect circular shape, avoiding the bulky lock mechanism found in models like the Ms Lori padlock or the steelwerksextreme variant. They were also reasonably priced; roughly 60 Euros for a pair with two keys that resembled sharp metal points. Since they billed in Euros, I assume the company is located somewhere within Europe. The URL has slipped my mind though, and I’d love to purchase one of these rings. Does anyone recall which site it was? Any assistance would be appreciated. Thanks
