For sale/wanted (Please be aware of scams) discussion

I’ve had my piercing done and now I’d like to adjust the ring sizes, going up or down so that eventually it can be used for chastity.

The piercer was contacted by me; they seemed a bit uninterested in selling other Rings, basically stating that their focus is just on doing the piercings . Could anyone recommend some good sites to purchase from? Perhaps purchasing a set would be better than buying them individually. Any advice would be gratefully appreciated thank you in advance
