"From now on, no more dirt." Newly developed, smudge-resistant core that keeps notebooks clean. Sharp replacement core 'uni' product features: - Clearly bold yet resistant to dirt (Smudge-Proof method). With a unique ingredient blend, the core powder adheres closely to the paper surface. It allows for writing in bold letters while keeping the notebook clean after writing. This replacement core is ideal for creating notebooks that can be referred to multiple times, as it suppresses dirt from friction between paper surfaces and contact with hands. *About the Smudge-Proof method: This is a manufacturing method for producing a core that suppresses dirt by adhering core powder to the paper surface with a unique ingredient blend. It is named after the English term Smudge-Proof, which means resistant to smudging and bleeding. It retains the traditional features of "strong," "bold," and "smooth," while adding the characteristic of being "dirt-resistant." - Minimal bleeding when using markers. When using highlighters or other markers, the spread of core powder is suppressed, making it less likely for 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 reveal the contents. It is designed in off-white to blend into living spaces, providing a simple and timeless case. The central circular indentation serves as a visual accent and a grip for sliding open and closing the case. - Easy core retrieval with a sliding case. The simple sliding operation allows for smooth retrieval of the core. *The spread of core powder due to friction after writing is defined as dirt 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, can also lead to differences in dirt suppression results.
