I have a severe allergy to anything in my ears. I took a chance and the first half hour my ears itched and burned. Now they are calming down. I hope they don't get anymore irritated. Was surprised how small they really are but it's fine. Less contact on earlobe. Posts are plenty long. Only problem was two of the studs were glued down. Can't get them out. Will update in a couple days. Ok don't even need to wait a couple days. My ears swelled up and are red and weepy. Do not but if you have sensitivities.
