There is something about sketching with biro that always seems to take me down a more fun and carefree path, maybe because it reminds me of when I was younger drawing gundam on scraps of paper, or the doodles I used to do all over my school books. I made this brush to try and capture the vibe of cheap supermarket biro's (ballpoint pens). To add to the authenticity I made a custom colour palette based on the 4 colour bic biros. This brush and others are available through my Kofi.
