[Sold Out] Astro Choking Check Pen

[Discontinued] Paper Drying Defect Check Pen 'Astro Chalking Check Pen'

The "Astro Chalking Check Pen" is a pen that allows you to confirm the risk of chalking due to the acidity of the paper. When printed on highly acidic paper, chalking can occur, where only the pigment components of the ink easily come off like powder when rubbing the dried print. Since printing can still be done on highly acidic paper, discovering chalking in the later stages can lead to significant losses due to reprinting. 【Features】 - You can easily check the risk of chalking by lightly applying the solution to the paper, helping to avoid troubles. - Its pen shape makes it portable, allowing for easy checks on the work site. - The degree of risk for chalking can be confirmed by differences in color development. *For more details, please refer to the PDF document or feel free to contact us.
