These are really cute and different, but I never wear them.  Since the pearls weigh down one end, they end up sliding out of your ear after just a little while.  I have tried putting a back on them (the small round silicone/plastic kind) but the stem is just too thick - they will hardly go on - to the point that it is tough to get them on the end, let alone over the entire stem and then to the chain where I could pull them up behind my earlobe, and who wants to see a plastic earing back hanging there?  I recommend the plain silver version of these without added items.
