It's a teen accessory store, but it was the closest thing around the house and I'm in a pinch for body jewelry.
My tongue ring ball fell off and I didn't have extras at home. I could see the white new tissue forming so I had to get something. Here, they have cheap sets of bars and also just packs of ball replacements.
Not all the designs in the packs were cute, but for $12 for 2 bars and like 8 ball designs, it's not bad at all.
