These are eyes made for Smart Doll boy size. They have some tracking. Materials include glass, acrylic, and resin. They are generally small, with a diameter of 14mm, made to fit the eye width as closely as possible. There are two versions: one with highlights and a "yami" (dark/sickly) version. ◎ They are designed to be less likely to appear sunken even when worn by dolls with heavy eyelids. ◎ Since these are not simply cut-out printed irises, there are no cut lines around the iris. The shallow curve of the cabochon means they can also be used with Dollfie Dream dolls. (The irises are smaller because they were made for Smart Doll boy size.) The color is cobalt blue. Please understand that the parts may have chips or small scratches, and as these are amateur handmade items, there may be resin bubbles or overflow.
