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.
 
Straight from Japan, this very cute but infinitely useful little fountain pen is refillable with cartridges (supplied with a pack of three, plus the one it comes with) and can travel anywhere, encased as it is in a robust spaceship-like cylinder. Its rotundness makes it comfy to hold, and if you pop the lid on the end it balances well for those who like a lengthier pen.
 
Strokes are fine as you would expect from a fountain pen with a steel nib, but this is fabulous to draw detailed work with. The ink is dense, and as you can see in the pictures, can be worked with using a water and brush.

Even the spare cartridges are in a cute little case, a little bit like a test tube.
 
Supplied with black ink, although because this is cartridge-based you could of course rinse it and put any colour in!
