The calligraphy pen, thanks to its comfortable handle, holds well, making it easy to create thin and thick lines with ease. The tip is felt, both durable and flexible, so your pen strokes will always be exactly as you want them. The quality water-based pigment is waterproof once dry and does not smudge. Bimoji pens are also suitable for etegami art. The line width is 0.6–3 mm.
