Kwark is a hand display font published by Hanoded.
Kwark is a nice, cartoonesque outline font with a bit of grunginess. Yes, it is an all caps font, but upper- and lowercase letters differ in shape, so you can mix and match.
The name is not really related to the way the font looks: kwark means ‘curd’ in Dutch. You think that sounds delicious? Well, then give Kwark a try!
