I read most of the reviews and was prepared for how dainty they were and that statement is accurate.  I think that as long as you treat them gently, they should be fine. They're as cute as can be and I really enjoy wearing them.  It took me a good ten minutes to untangle them from the box, but other than that, I'm very pleased with this purchase. Extremely good value for the money!

Update: The post is pretty weak, I bent one while trying to put the back on & was able to bend it back. The chain is a little shorter & the hearts are smaller than I pictured, too.  Still like them, but they really do have to be handled with care.
