The Tombow ABT Dual Brush Pen has a fine tip perfect for consistent lines and tight drawings, complemented by a highly flexible brush tip which is soft yet durable. Tombow ABT's are water-based and so odourless, non-toxic and acid free. They work like watercolour paints and blend effortlessly. These pens are widely used for rubber-stamping, card-making and as artists' watercolour pens. The Dual Brush Pen is also used by comic book designers and graphic artists. USE IT IN TWO WAYS: The fine tip is used wherever precise lines are required. The second tip is a flexible brush tip, the thickness of which varies depending on the pressure applied. SPECIAL ADVANTAGES: The ABT is a brush pen, so you don't have to decide whether to use a pen or a brush – you simply have both. You can paint and draw evenly without running out of paint. UNLIMITED CREATIVITY: Express your creativity and use our dual brush pens for hand lettering, watercolor, illustrations, bullet journaling, stamping, drawing mangas and mandalas. WATER-BASED: The colors can be mixed with each other and can be used to create beautiful color gradients in a watercolor technique. They are acid-free, non-toxic and odorless. CONSTANCY AND TRADITION: Tombow is a Japanese family business that manufactures high-quality and reliable writing instruments, supporting creative people in their work.
