I got eyes in the mail last night! Yay!
The Eyeco glass eyes arrived last night - they seem like they might be a bit of a pain to reposition, but they are otherwise PERFECT. They're a wonderful colour for Claire (still green, but a more natural looking shade) and the size is exactly what I wanted. No gappage, like there was with the 12mm acrylics, and the eye itself is properly sized. She won't look quite so ...err...manga as she did with the eyes she came with.
Of course, now I need a pair for Sebastian, too!
ETA Sunday: Here's a picture!
