Custom short ones from Anatometal. I have 3/16" wearable in my skinny conches and they're perfect. When I wear standard IS eyelets, my eyelets stick out pretty far in front and look like they're about to fall out. They're not but they look like it.
Current: 3/4" lobes, 4g conches, 2g flats, 16g rooks, 18g nostrils, 8g septum, 8g nipples
Past: Too many to count.
Future: Who knows?
