If I end up selling any of my own jewelry, I'll definitely try to buy a pair of those. They gross me out, but I won't have to look at them if they're in my ears, just get lots of pretty compliments. 8D
Ouch...hmm, five euros, right? then there's the shipping to america and up to south dakota..that would be...a lot. *sighs* maybe once i get a job i can look again. They really are interesting and i think you have a great idea here!
