Tombow ABT Dual Brush Pens feature a flexible brush tip and a fine tip in one marker. The brush tip works like a paintbrush to create fine, medium, or bold strokes, while the fine tip provides consistent lines for details. The water-based ink is blendable, odorless, non-bleeding, and acid-free, making them ideal for coloring, fine art, illustrations, doodling, journaling, and hand lettering. ## Sources - [homepage](https://tombowusa.com/)
