I dont believe it to be frank with you. Also here comes a little bit of gloating on my part, i have been wearing a tasche necklace everyday for an entire year. If you dont believe me, ask my mother.
Mine has gone a bit funny now, the chain has lost its silverness and is kinda a bit coppery and the acyrlic has dappled, but i will never ever ever not wear it (except in the bath and shower, i sleep in it too).
Also they have it in a ring
