I'm selling this because I haven't had a chance to use it after purchasing it (*u_u) This is a set of vertical earring converters to convert pierced earrings to clip-on earrings, along with silicone covers. It's compatible with titanium posts, stainless steel posts, resin posts, metal hooks, resin hooks (slim types), straight stud earrings, dangle earrings, and back catch earrings. Materials: Brass (plated) and resin. Colors: Gold and Silver. Quantity: 6 pairs (3 pairs of each color). Size: Please refer to the image. It's very easy to use: simply bend the earring post slightly, insert it into the converter hole, and you can easily transform your pierced earrings into butterfly-clasp clip-on earrings. Recommended for those who don't have pierced ears. Comes with silicone covers to prevent earlobe pain. * Not suitable for chain-type earrings like American earrings, soft resin earrings, extremely thick posts, or heavy earrings. * Metal hooks may be a bit tight depending on their shape and size. * Please insert the earrings slowly to avoid breakage. * Repeatedly inserting and removing earrings may loosen the catch. Please check that the earrings won't fall out before use. Color: Gold系 Color: Silver系
