I picked up a new 4-colour ballpoint pen from the Japan Centre in London when I was in the city a couple of weeks ago for a hospital appointment. I obviously had to try it out on a portrait, so I drew Alexander from the Museum by Sktchy app.
The pen is a Tombow and has the usual 4 colours – black, blue, red and green. It has a lovely line – its lighter in tone and thinner than a Bic so it’s easier to create a gentle build up of colour. Having said that, the ink does blob much more than Bics do, so I had to clean the nib much more than I have to when using Bics and I still found blobs crept into my sketch, as you can see. So there’s not much to choose between the two brands for me – though Bics would still be my go to because of the wider range of colours.
