Rat Infested Mailbox by David Kerkhoff is a free handwritten display font with tall, uneven letters and a restless scrawled line. Its strokes shift between thin scratches and blunt inked patches, with rough breaks that look hurried and physical.
Packaging is a strong setting for its raw homemade edge, especially hot sauce labels and underground music merchandise. It also suits horror posters and punk event graphics. In branding, the lettering can become a nervous hand-mark instead of a polished logo.
