I'm an engineering professor and have enjoyed purchasing these for myself, colleagues and students. They're just the right size and beautifully made. I love wearing them and my students seem to as well - one student has been wearing them every time I've seen her since.
I absolutley adore these earrings. They are so much fun. You can barely tell their screws unless you look real close. I plan to get a lot of use out of them as you can wear them casually or to work.
