Review (5/5): I have birds and they love to bite shiny things
I have birds and they love to bite shiny things. If I don't wear earrings my holes close up. So, I needed to have earrings that could stay in and be sort of bird proof -- they have bitten through hollow earrings and put dents in others.
These work! They are solid and very comfortable to wear all the time.
Now if I could only get the birds to understand, "Leave it".
