High-performance yo-yo string with a "grip guard" sleeve to protect your finger from injury during play. At the time, there was a pending patent assigned to this product. However, I could not find if the patent was officially issued.

The blacked out portion on the back of the card read, 800-525-YOYO www.yoyozone.com
