I am obsessed with these open huggies! They are dainty yet sturdy, and they're easy to adjust to the right size. I got the 5-7 mm ones so I could wear them in my third piercings. The instructions say to keep them away from water, but I've honestly had no problem showering and sleeping in these for over two weeks. I have also had no problems with them slipping out - they stay in well. I HIGHLY recommend these to anyone who gets irritation from earrings with standard backings. No backing = no problem.
