Teranishi Rushon Petite Pen 0.3 mm – Bright (Pack of 12)

Teranishi's Rushon Petite Pen is somewhat of a hidden gem in the West, something Komadori of course wants to change – after all, this is a fantastic Japanese fineliner. This water-based fineliner comes in a variety of colors – 36 to be exact. In addition to being great for notes, it's also great for coloring.

This set includes the colors: bright yellow, deep red, dark brown, dark gray, eggplant, emerald, olive, persimmon, plum, sapphire, ultramarine, and cinnabar.

More colors (as well as the opportunity to buy them individually) can be found here.
