They look nice but are a real pain to get in. I've had my ears pierced for about 20 years now and these holes used to be 6 mm in diameter (they have now shrunk back to 'normal') so you'd expect them to be suitable for all kinds of earwires. Sadly, these earwires are too tricky to get in so I will need to find another solution. I am considering silver wire to make my own hooks for the pendants I've made.

These are more substantial than i expected which was a nice surprise. Will look lovely when i have created the earrings :)
