STIKFAS™ are 3 1/4-inch (8 cm) model assembly figures/toys. Once built they can be customized with stickers (packaged as Stikers) and different pieces. The design principle behind a STIKFAS is that all of the joints are ball/socket, and offer exceptional poseability, interchangeability, and articulation. They are sold as "kits" that include accessories, and Stikers, and additional models (dragon, dog, cat, bike, horse, octopus...) to accentuate the "theme" of each kit.
