Mitsubishi Pencil MITSUBISHI PENCIL U052031PHB13 [Limited Kurutoga Sharp Refill HB 0.5mm] (10 sets)
Structure of Kurutoga refill
Conventional cores have a hard outer layer and a soft inner layer. On the other hand, Kurtoga refills use a unique new manufacturing method to create a structure where the inside of the core is hard and the outside is soft.
Therefore, the inside part is hard to scrape and the outside part is easy to scrape, making it easy to toggle and write smoothly.
*You can also use sharpeners other than Kurtoga, but the lead alone will not trigger.
●Case color: pink
