[Sharp core that is easier to use, less likely to break, and pursues a thick, smooth writing experience] We continued to pursue the development of cores with new formulations and new manufacturing methods, and succeeded in commercializing refills that are easier to use, less likely to break, thicker, and smoother. The UNi refill, which was reborn using this new SHU manufacturing method, not only achieved an approximately 20% increase in strength compared to conventional cores, but also achieved a smooth writing feel and suppleness that is hard to break. The fact that there is little core loss is also economical.
