The Roku chalk project began because chalk is the critical addition needed to realize the full performance of your tip.From the beginning, there were three main objectives of this project. The first objective is to ensure high quality chalk, which has grip power, adhesion, and solidity, since those are the most important performance factors. The second is the concept of hexagonal close-packed structure. The third is that it has to be hexagonal shape to symbolize the close-packed structure of the chalk itself.After a long development period since the release ofKamui 0.98and1.21, the chalk exemplifying the target criteria has been created. From the development objectives and concept, it is named ROKU. In Japanese, it means hexagon. Sold individually as one piece. The next level of chalk from Kamui
