Where can you buy clear retainers for your belly piercing?

I would go to Body Art Forms. I've ordered from them many times and so have a lot of my friends. They're very reputable and have amazing customer service and shipping times. I'll attach the link.

-If your piercing is 14ga, you can buy the navel retainers but if it's 16ga, get the eyebrow retainer. Same shape so its fine.
