Review on 👓 Versatile Eyeglasses Retainer: Adjustable Sunglass Holder for Prescription Glasses by David Silva

For some reason I thought it was a braided strap. It's actually a piece of leather. There were four in the pack, adjustable and seem to be pretty sturdy so far. Bought these for my mom who has a habit of putting on glasses and losing them. She hasn't lost her glasses since using the cord. Not sure how comfortable it is to wear for long periods - a smoother braided synthetic line might be better.
