Low Priced 3

What can you write about eyeglass cords? They serve their purpose. The fortifications on the glasses are drumrum simple black O-rings with a spiral spring.
The price / performance ratio is ok.

Addendum:
Did the cords now two months in use and they are great! The loops are not too large as another customer complained. You just have to push the coil spring on the O-ring in the direction of temple and the loop is closed.
