Mitsubishi Pencil Sharp Lead uni 0.5 HB 3 pieces ULS05403PHB Black

"From now on, no more dirt." Newly developed, a core that strongly adheres to keep notebooks clean. Sharp replacement core 'uni' product features: - Clearly bold yet resistant to dirt (Smudge-Proof technology). The unique ingredient formulation allows core powder to adhere closely to the paper surface. It enables writing in clearly bold letters while being resistant to smudging, keeping your notebook clean after writing. This replacement core is ideal for creating notebooks that you will refer back to multiple times, as it suppresses dirt from friction between paper surfaces and contact with hands. *About Smudge-Proof technology: This is a manufacturing method for producing a core that suppresses dirt by closely adhering core powder to the paper surface using a unique ingredient formulation. It is named after the English term Smudge-Proof, meaning resistant to smudging and bleeding. It retains the characteristics of being "strong," "bold," and "smooth" from conventional products while adding the feature of being "dirt-resistant." - Difficult to smudge even when using markers: Even when using highlighters or other markers, the spread of core powder is suppressed, making it difficult for letters to bleed and preventing dirt on the paper surface. Additionally, it reduces dirt caused by core powder adhering to the tips of markers. - Simple design case: The case features an opaque, matte texture that intentionally does not reveal its contents. The design, based on off-white, blends well into living spaces regardless of core diameter, offering a simple and timeless case. The central circular indentation serves as a visual accent and provides a grip for sliding the case open and closed. - Easy core retrieval with a sliding case: The simple sliding operation allows for smooth retrieval of the core. *Dirt from 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 result in differences in dirt suppression. 【Smudge-Proof technology】 A method for producing a core that suppresses dirt by closely adhering core powder to the paper surface using a unique ingredient formulation. 【Core diameter】 0.5mm 【Hardness】 HB 【Quantity】 40 pieces x 3 packs 【Body size】 76mm x 20mm x 7mm
