Structure and Cosmetics

I imagine this would be really uncomfortable to sleep on, and my hair would get caught on it all the time, but I need this.
Where can I find it?

I am disappointed that it's an actual earring and not actually for gauged ears though. The diameter looks like the perfect fit for the gauge my ears are at right now.
