About
The MonsterShell is a 2010 Japan-exclusive re-release of Yomega’s All-Star under the third Hyper Yo-Yo umbrella. Its fixed metal axle gives it a strong, snappy return response ideal for beginners learning Forward Pass and Breakaway. The non-disassembling body needs no maintenance beyond string replacement. Available in multiple colorways including Clear Red and Pink/White, the MonsterShell was notably used by competitive player Ryuji of the Top Spinners group. Packaged with red string and a certification-eligible instruction manual.
