These are 2.5mmx2mm so they're perfect even on my tiny nail beds.
I have featured one on each nail and made my accent nail the main focus. They can be attached with nail glue or clear polish, I used clear polish.
The polish I'm wearing is Eat. Sleep. Polish. - Don't Pet the Cheshire Cat. A purple crelly with purple and white glitters. This is 3 coats.
These studs are fab and the gold contrasts really well against the purple. They're just a nice size so they can be worn without being obstructive. Awesome!
