Faber-Castell Pitt Artist Brush Pens offer a range of vibrant pigmented India ink in two distinct brush tips. The standard Brush Pen is slightly firmer and designed for medium-sized strokes, making it versatile for general use in calligraphy and illustration. The Soft Brush pen nibs are more flexible which allows it to expand or flex more when pressure is applied, creating broader strokes than the standard brush pen can achieve. - Faber-Castell Pitt Artist Pens - Studio Gift Box, Set of 12Faber Castell Pitt Artists Pen, 12CT GIFT BOX - Includes one each 107 Cadmium Yellow, 110 Phthalo Blue, 112 Leaf Green, Orange Glaze, 121 Pale Geranium Lake, 125 Middle Purple Pink, 136 Purple Violet, 146 Sky Blue, 169 Caput Mortuum, 199 Black, 232 Cold Grey III, and 264 Dark Phthalo Green in a gift box
