Hard-to-break, dark, smooth replacement core [Sharp core that is easier to use, harder to break, darker, and has a smoother writing feel] We continue to pursue the development of new formulations and new manufacturing methods, making it easier to use and harder to break. We have succeeded in commercializing a thick and smooth replacement core. The uni replacement core, which was reborn by this new technology SHU manufacturing method, not only achieved a strength increase of about 20% compared to the conventional core, but also realized a smooth writing taste and suppleness that is hard to break. It is also economical that there is little loss of core.
