Marvy Uchida LePen 4300-10P Micro Fine 0.3mm Fineliner, 10 Pen Set Pastel Colors

Engineered with premium, non-toxic, and acid-free water-based dye ink, the Le Pen series is optimized for high-performance writing on standard paper and thin organizer inserts. Best of all, it restricts heavy ink saturation, ensuring that your vibrant, high-contrast notes will not bleed through to ruin the reverse side of the sheet.
