Please review the profile before considering a purchase. This is an unused necklace that was purchased and stored in a zip-top bag. It is made of plastic beads. There is no clasp. I think it can be used as is, in a long state, or doubled. It is approximately 70cm long when fully extended. There may be a difference in color between the photos and the actual item. Although it is unused, it has been stored at home for a while, so please consider this before purchasing.
