Smooth core that is easy to toggle

With its unique core rotation function, it is a core that can be easily and smoothly written when used with the sharp “Kurutoga” that keeps the core rotating and toggling. Since the outside of the core is soft, the core is easy to toggle and you can write smoothly.

conventional core has a structure that is hard on the outside and soft on the inside. On the other hand, the Kurtuga replacement core uses a unique new manufacturing method to create a structure in which the inside of the core is hard and the outside is soft. Therefore, the inside is hard to scrape and the outside is easy to scrape, so it is easy to scratch and you can write smoothly.

* Although it can be used with sharps other than Kurtoga, it does not work with the core alone.
