Simple design that allows you to use your favorite leadBased on the mechanical pencil refill "uni", we have eliminated the indication of lead diameter and hardness to create a simpler design. After using up the lead (0.5HB) that comes with the product, you can refill it with a lead of your favorite diameter and hardness. Soft colors that expand the coordination inside your pen caseThe color of the case for mechanical pencil refills is generally determined by the hardness, but the "uni Color Case" offers new options for case colors. By expanding the options, such as choosing the color to match the shaft color of the mechanical pencil you usually use or the color of your pen case, we support you in studying with a more positive attitude. The three colors released this time are soft colors that match the simple design and fit in various situations.
