566-PIECE STEAM CONSTRUCTION SYSTEM
A comprehensive 566-piece building system combines 25 construction shapes with eight accessory types. Straight and curved boards, gears, connectors, pulleys and reusable nuts and bolts provide extensive possibilities for vehicles, structures, machines and collaborative preschool engineering projects.
25 SHAPES FOR OPEN-ENDED ENGINEERING
Multiple board lengths combine with curved pieces, gears, Y-shapes, anchors, steering-wheel forms and other specialized components. The varied geometry encourages children to experiment with connection angles, structural relationships, symmetry and creative mechanical designs through hands-on construction.
GEARS โข PULLEYS โข ROPES โข CONNECTORS
Three gear sizes, pulleys, ropes, buckets and multiple nut-and-bolt connectors introduce mechanical ideas into open-ended building. Children can assemble, test, adjust and rebuild structures while exploring movement, connection, lifting and basic engineering relationships.
BUILT FOR COLLABORATIVE STEAM PLAY
Construction boards reach up to 88 cm long and 1.5 cm thick, supporting substantial floor-based models and group projects. Two storage carts help organize the complete system for repeated use in preschools, kindergartens and dedicated construction areas.
