The Black Genuine Leather Cord is strong and durable. The clasp is sturdy as well...I don't forsee any problems regarding the longevity of this leather cord.  It is easy to clasp and unclasp  and there are not issues regarding using it with smaler or larger pendants as long as the bail can accomodate the size of the clasp and leather cord. Also the cord is not so thick that a woman can't wear it either. I'll be using it with larger pendants to accomodate the guage of the cord. I highly recommend this necklace to anyone who may be unsure about its craftsmanship or durablility. This leather necklace is made with quality materials that is crafted and designed to provide the buyer with many years of use. Great purchase!
