Wear this cool belly ring in the color of your choice in the sun during the day, then show it off as it glows at night! There's nothing worse than buying a new piece of jewelry and then not being able to see it, right? We have solved that issue. Now you can draw attention to your favorite piercing even in the dark! Mix and match this piece with the balls off of our Tribal Print Straight Barbells too for a matching tongue/belly button glow and tribal mix up! These are 14 gauge, 7/16" (11mm) with a 5mm top and 8mm bottom ball. They are surgical steel and acrylic!
