Bought this years ago and this is what I learned: the item is great for the price but it is definitely not something you can wear for longer than a few hours (which should probably be expected with something like this).  Don't try wearing it to bed, and don't try to keep it in all of the time like you can with most earrings.  You must adjust the size of the dragon to fit your ear which is fairly easy to do, but be careful that you don't overdo it and snap the dragon in 2.
