The Tombow ABT Dual Brush Pen features a fine tip for precise lines and drawings, along with a flexible brush tip that is both soft and durable. These water-based pens are odorless, non-toxic, and acid-free, allowing them to blend effortlessly like watercolors. They are ideal for rubber-stamping, card-making, watercolor art, comic book design, and graphic artistry. The pen offers two ways to use it: a fine tip for precise lines and a brush tip that varies in thickness based on pressure. This dual functionality means you have both a pen and a brush in one, ensuring consistent drawing without running out of ink. Unleash your creativity with these dual brush pens for hand lettering, watercolor painting, illustrations, bullet journaling, stamping, and drawing manga and mandalas. The water-based colors can be mixed and blended to create beautiful watercolor gradients.
