My driving glasses are red and so i use these on them when i get out of the car so I do not lose them. They do make you feel a little special and look special-really useful and also work as an attractive accessory.
The beaded cords arrived very quickly after purchase. They were well packaged inside bubble-wrap. The beads are subtle and placed tightly together on the cord and the ends of the straps have a good tightening fixture that ensures the cords stay on the arms of the spectacles without loosening and falling off. Good value for money.
