A MASTERPIECE OF HIGH-ORDER MOD ENGINEERING! Designed and crafted by Xu, the Bump Meson Cube 6x6x6 is an incredible custom twisty puzzle built around a 6x6 core and adapted with precision 3D-printed extensions. Although it resembles a standard 4x4 at a glance, its rotation mechanics are entirely different (referencing the early ShengShou 4x4 prototype concept, where the center piece is uniquely tailored for this edition). It delivers an exceptionally difficult, mind-bending solving experience and makes a stunning centerpiece for any serious puzzle collection! Key Performance Features: High-Order Meson Mechanism: Built upon a robust 6x6 core combined with specialized 3D-printed structural modifications. Imposing Size & Weight: Measures 7.4 x 7.4 x 7.4 cm with a net weight of 282.8 g for a solid, substantial feel in hand. Premium Materials: Fabricated using a durable combination of ABS components and 3D printed PLA extensions.
