Kukuxumusu's designs are distinctive for their style and humor. Incorporating environmental, social and cultural issues there is often a slight sexual undertone. One of their notable tee-shirt designs is a peace sign covered VW van ‘humping’ a tank. Humans and animals often reverse roles to create ironic storylines ie: the bulls will be chasing the humans. Their desings incorperate many Basque symbols staying true to their roots. Kukuxumusu also creates custom designs for companies, sports teams and groups.
