Thank you for viewing! (*‘ω‘ *) These are handmade earrings made with hotaru glass. They are made with surgical stainless steel parts. The hotaru glass is 8mm in size. It's very beautiful ✨ I make them carefully, but since they are handmade by an amateur, they are not perfect. They are also not very strong, so please handle them gently (ｕ_ｕ*) Instant purchase is OK ♪︎♪︎ I also sell seaglass earrings and Ryukyu glass earrings, so please take a look (*^-^) Type... One-grain Base material... Surgical stainless steel
