"From now on, no more dirt." Newly developed, smudge-resistant core that keeps notebooks clean. Sharp replacement core 'uni' product features: - Clear and dark yet resistant to dirt (Smudge-Proof manufacturing method). With a unique blend of ingredients, core powder adheres closely to the paper surface. This allows for writing clear and dark characters while keeping the notebook clean after writing. It is ideal for creating notebooks that you will refer to multiple times, as it suppresses dirt from paper-to-paper friction and hand contact. *About the Smudge-Proof manufacturing method: This method produces a core that adheres closely to the paper surface to suppress dirt by using a unique blend of ingredients. 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." - Markers do not bleed easily. Even when using highlighters or other markers, the spread of core powder is suppressed, preventing smudging 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 and matte texture that intentionally does not show the contents. The off-white design blends into living spaces regardless of core diameter, creating a simple and timeless case. The circular indentation in the center serves as a visual accent and provides a grip for sliding the case open and closed. - Easy core extraction with a sliding case. The simple sliding operation allows for smooth core extraction. *Dirt from writing-related friction 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 impact results. 【Smudge-Proof manufacturing method】 A method for producing a core that adheres closely to the paper surface to suppress dirt using a unique blend of ingredients. 【Core diameter】 0.3mm 【Hardness】 B 【Quantity】 25 pieces x 3 packs 【Body size】 76mm x 20mm x 7mm / Weight 5.6g 【Pack size】 140mm x 74mm x 7mm / Weight 18g 【
