Mondo will also be bringing Madballs pins, based on the popular 1980’s gross-out toy line that went on to span everything from a video game to TV shows. Now, Mondo is bringing the fun and colourful characters to life after 30 years. The series kicks off with a series of enamel pins based directly on the original art of Series 1, and will continue with a line of updated collectible balls. They will retail for $10 each.
