16mm/7mm doll eyes with amethyst in the iris. For yellowing prevention, the whites of the eyes and the coating use Padico's Resin Shine Drop, Gem Drop White, and Shine Drop Gloss. There may be fine air bubbles, and the edges and backs may not be perfectly finished. Also, due to the nature of resin, it may break if strong force is applied. Natural stones may have slight color variations, inclusions, and cracks, but please understand that these are part of the charm of natural stones. Due to digital images, the color may differ from the actual product, and considering that these are handmade items, please refrain from purchasing if you are looking for perfection.
