450-PIECE LARGE CONSTRUCTION SYSTEM
A substantial 450-piece building system combines oversized New Zealand pine components with reusable nuts, bolts, wheels and connectors. Children can assemble large vehicles, structures and mechanical creations while exploring construction, spatial relationships and collaborative problem-solving.
EXTRA-LARGE 100 CM BUILDING PIECES
Construction boards extend up to 100 cm long and use a substantial 2.5 cm thickness, allowing children to move beyond tabletop models into large floor-based projects that encourage whole-body interaction, planning and cooperative building.
WOOD • WHEELS • PULLEYS • CONNECTORS
Straight boards, curved pieces, ABS corner connectors, wheels, pulleys, ropes and large reusable nuts and bolts create multiple construction possibilities. Children can experiment with movement, connection angles and structural relationships through hands-on mechanical building.
BUILT FOR COLLABORATIVE STEAM PLAY
The large component format naturally encourages several children to plan and build together. Repeated assembling, adjusting and rebuilding provides opportunities to develop spatial reasoning, engineering thinking, coordination, creativity and communication through open-ended construction.
