Check Pen Alpha - (Green) WYT20-G

Product number: WYT20-G Line width: Fine 1.2mm / Bold 3.5-4.0mm. Dual-use green for thick and thin lines. Ink type: Disposable water-based dye. This checker pen produces a beautiful finish that won't bleed through to the back of the paper. The ink is smudge-resistant on the back, so you can use it while keeping your notebooks and workbooks neat and easy to read. The bold pen features a flexible nib that fits comfortably on the paper for easy writing. Choose from four colors, including colorful blue and pink. Covering the blue/green ink with a red sheet, or the red/pink ink with a green sheet, will hide the text.
