These are handmade doll eyes. They are resin eyes made using resin. Size: 20mm ⚠️ Commercial molds are used. Due to resin shrinkage, there may be a variation of +0.5mm to -0.5mm from the listed size. The irises are hand-carved, so no two pieces will be exactly alike. A top coat is applied to prevent yellowing. ※ These are amateur handmade products, so thank you for your understanding.
