This creative, double-sided marker creates thick or thin lines with two tip choices--a broad bullet tip for bold lines, or an extra-fine tip for detailed, precise lines. Perfect for color-coding and decorating planners, journals and notebooks. Create fun doodling and lettering styles with a choice of 24 colors. Water-based ink doesn't bleed through most papers. Durable fiber point tips are long lasting and maintain shape even with repeated use. Bullet tip 0.8mm; extra-fine tip 0.3mm.
