390-PIECE COLORFUL CONSTRUCTION SET
A large 390-piece construction system with 26 different building shapes encourages children to combine, connect and rebuild imaginative structures. Colorful components and reusable bolt-and-nut connections support open-ended floor construction, creative experimentation and collaborative preschool building activities.
26 SHAPES FOR OPEN-ENDED BUILDING
A varied selection of straight, curved and shaped construction pieces gives children more possibilities for creating animals, vehicles, structures and abstract mechanical models. Different forms encourage children to explore geometry, spatial relationships and multiple ways of connecting components.
COLORFUL MECHANICAL CONSTRUCTION PLAY
Natural wood tones combine with bright colors to make each construction visually engaging. Children can repeatedly assemble, adjust and rebuild their creations, turning hands-on construction into an active process of planning, problem-solving, experimentation and early engineering exploration.
LARGE PIECES FOR COLLABORATIVE PLAY
With components measuring up to 58.9 cm long, the set supports substantial floor-based constructions rather than only small tabletop models. The larger format creates opportunities for children to build together while practicing coordination, communication and collaborative problem-solving.
