If you love to write calligraphy or are a free-hand artist, you're going to want the Black Pigma Brush Pen by Sakura! This pen has waterproof, quick-drying pigment ink that does not feather or bleed through even the thinnest of papers. Once the ink is dry, you will see no smearing and the ink is fade proof against sunlight or UV light. Included in the package is one black brush pen that has a fine point, is flexible, and features a brush-style nib.
