It is named after the English term Smudge-Proof, meaning resistant to smudging and bleeding. It retains the traditional features of "strong," "dark," and "smooth," while adding the characteristic of being "dirt-resistant." - Resistant to bleeding even when using markers. When using highlighters or other markers, the spread of core powder is suppressed, making it less likely for the letters to bleed and keeping the paper clean. Additionally, it reduces dirt caused by core powder adhering to the marker tip. - Simple design case. The case features an opaque, matte texture that intentionally does not show the contents. It has a design based on off-white that blends well into living spaces, making it simple and timeless. The central circular indentation provides a visual accent and serves as a grip for sliding the case open and closed. - Easy core retrieval with a sliding case. The simple sliding operation allows for smooth core retrieval. *Dirt caused by friction after writing is defined as the spread of core powder on the paper surface. Under certain conditions, it suppresses dirt by up to 50% compared to conventional products. Differences in core diameter, hardness, paper type, writing pressure, and other conditions may affect dirt suppression results. Variations in sebum and moisture levels, as well as the strength of contact, may also lead to differences in dirt suppression results. 【Smudge-Proof manufacturing method】 A method for producing tightly adhering cores that suppress dirt by making the core powder adhere to the paper surface with a unique ingredient blend. 【Core diameter】 0.5mm 【Hardness】 B 【Quantity】 40 pieces × 3 packs 【Body size】 76mm (height) × 20mm (width) ×
