The PITT artist pen by Faber-Castell combines the vibrancy and permanence of traditional India drawing ink with the convenience of a modern disposable pen. The pigmented and lightfast drawing ink is ideal for sketches, drawings, layouts, fashion design, and illustration. The ink is also water-resistant, permanent, odor-free, acid-free, and pH neutral.

The asterisks on the pen barrel specify the level of lightfastness:
*** = maximum (100+ years)
** = very good (25+ years)
* = good (5+ years)

This set of White 101 *** pens contains four tip sizes: B (Brush), C (Chisel), 1.5 (1.5 mm Bullet), and 2.5 (2.5 mm Bullet).

Note: PITT artist pens should be stored horizontally for best performance. If the ink appears darker than it should, store the pen horizontally or tip up for a day or two.
