These beautiful labrets twinkle like a star. The stud is made out of 14-carat gold, which will catch the light and shine beautifully. This small star design is dainty, while still standing out. The gold stud fits into a bio-plast bar. Bio-plast is a bio-compatible plastic, which is perfect for someone with metal allergies. Additionally, bio-plast is very comfortable to wear since it is slightly flexible. While people typically wear labrets in lip piercings, they will also fit other types of piercings. These labrets are 16 gauge/ 1.2 mm which is also suitable for a variety of ear cartilage piercings. For example: tragus, flat and helix piercings. Another advantage of bio-plast is that you can cut them to whatever length you need, so they will always fit perfectly.
