All the stationery in my shop is drawn from my own holster. Sharing my illustration toolbox with you, these items are my personal favourites, go-tos for myriad illustration and lettering jobs.
 
The Pentel Touch Artist Sign Pen is a 'fudenosuke' or brush pen, but is a little different from its basic counterpart, the Sign Pen. It has a very soft, longer brush tip - very fine indeed, but with pressure it delivers a bewildering range of line widths from whispery hair's breadth to fat gnarly strokes. If you pack only one pen to ravel with, this might be it.

Excellent for illustrating, sketching, lettering, calligraphy. My Vimeo channel has demos of most of the pens I keep in stock, if you want to see them in action (vimeo.com/inkymole)
