KAMUI Roku Chalk

KAMUI Roku Chalk, named “ROKU”, which is Japanese for Hexagon

The Roku Chalk project was initiated to unlock the full potential of KAMUI tips, recognizing that high-quality chalk is essential for optimal performance. After thousands of trials, the need for iterative improvement became clear. The project had three main objectives: to create chalk with superior grip power, adhesion, and solidity; to incorporate the concept of a “hexagonal close-packed structure”; and to design the chalk in a hexagonal shape to symbolize this structure. After extensive development, the perfect chalk was created, meeting all the criteria for enhancing the KAMUI tips.
