The best part of the piece is that it can be worn as a choker, necklace and even a bracelet...
yes you are right. It is a multi purpose necklace which can go with all your needs and demands. But, I think it would be better if we can only use it as a necklace.
I have recently went through it and found it really very amazing. It is also not of much price so, it is easily affordable. So, go for it...
