STATIC BALL STORAGE MODULE – This module stores the track ball steel balls, which not only meets the dynamic entertainment, but also presents another kind of industrial rational aesthetics in the static state. It customizes the “rokr” metal logo nameplate, highlight the polishing process, and match with four pure copper hand screws to make the hard core industrial wind jump on the top.


Night City Story

It takes “future technology” as the creative source and the orbital ball as the carrier to show the rigid mechanical structure to the public and feel the order pleasure of the steel ball rolling. It adopts a wood grain dip dyeing process and metal screen printing technology to dye the wood board with high-grade gray-black while retaining the original wood grain, giving it a metal texture and an overall profound future style. High permeability acrylic materials are innovatively added to achieve the “suspended” track effect to show more transparent expressiveness. Additionally, the traditional mortise and tenon technology and gear transmission combination are adopted so that the trackball can operate without power. More tracks are added so players can stimulate brainstorming, and feel the precision engineering structure.
