Details: • Available in multiple colors(36 vibrant colors) • Dual tip(1-2mm soft brush tip & 0.4mm fine tip) • Non-bleeding ink, perfect for coloring books and journaling • Acid-free & non-toxic water-based ink • The ink is water-soluble and you can achieve beautiful watercolor effects by pre-wetting an area first with an aqua brush pen (not included) and then color the area with the colors you want to blend. Note: Since it needs water to blend the colors, please use watercolor paper or mix media paper to prevent bleeding.
