These royal blue eyes feature a realistic iris texture and round doll like shape in the fashion of asian balljointed dolls. The 14mm series features a small pupil and iris with alot of eyewhites showing while the 18mm features a large anime/doll-esque pupil and iris for a more youthful or innocent look. Other than that the two are identicle. If you enjoyed these eyes please comment/rate. Thank you!
