This is a standard Duncan Freehand Zero, but with a difference. It is one of the Signature Freehand Zeros of the the performers Atsushi Yamada and Sojun Miyamura. Atsushi + Sojun, hence the A and S on the yo-yo cap. These were only sold at briefly at one online store overseas, and mainly at yo-yo events in Hokkaido when the team was demonstrating. Another great and collectible Freehand Zero from Japan.
