YANK
WEARING GLASSES CAN INCREASE IQ BY UP TO 15 POINTS
The Yank, made of flexible,
space-age DuPont 109 Nylon

steel.

The nylon Yank is never
harmed by perspiration, body
acids, or hair products. It
won't fade or burn and is
almost indestructible..


Originally used for prison and
military use, these frames are
hardy and durable. Don't their
flexibility and light weight
fool you - they are not rigid
