Astro High-Quality and Medium-Quality Paper Check Pen

A detection pen that can easily distinguish between high-quality paper and medium-quality paper based on the color when written with a pen.

The "Astro Quality and Medium Quality Paper Check Pen" is a product that allows for easy differentiation between quality and medium quality paper based on the color when applied with the pen. Medium quality paper contains components that react to ultraviolet light, causing fading or discoloration when exposed to sunlight. To protect important books and documents from fading or discoloration, Nikkengaku has developed a pen that allows for easy identification of paper types. 【Features】 - Differentiation can be performed simply by lightly applying the reagent to the paper. - For quality paper, there is no color change and it remains colorless, while medium quality paper changes to a reddish-purple color. - The more ground pulp contained in the paper, the darker the color change, so the intensity of the color serves as a guideline. *For more details, please refer to the PDF document or feel free to contact us.

Astro Neutral Paper Check Pen

A check pen that can easily distinguish between neutral paper and acidic paper.

The "Astro Neutral Paper Check Pen" is a product that allows for easy differentiation between neutral and acidic paper. Traditionally, concerns have been raised about the preservation issues of commonly used acidic paper (such as yellowing and damage due to oxidation), leading to a significant increase in the use of neutral paper. In places where books are managed, it is used to identify important documents made from acidic paper so that they can be recreated using neutral paper, or to reconsider the management methods of books. In the printing industry, it is used to easily distinguish between acidic and neutral paper with different printing suitability, helping to prevent printing troubles before they occur. 【Features】 ■ Allows differentiation of neutral paper without using pH meters or similar devices ■ Lightly apply the reagent to the paper you want to identify, and differentiation can be made based on the color *For more details, please refer to the PDF document or feel free to contact us.
