This is a YONEX carbonex3 manufactured from 1977 to 78. I believe this is a special racket, also introduced as the starting racket on the official YONEX X. It was the first YONEX racket to use carbon for the shaft (carbon wrap on a steel shaft). I think it's a rare racket that is not often seen on the market. Although it is an old item, there are no noticeable scratches or stains. Please understand that this is based on a layman's observation, and we appreciate your purchase.
