900-PIECE LARGE-SCALE CONSTRUCTION SYSTEM
A comprehensive 900-piece building system combines oversized New Zealand pine components, large wheels, ABS connectors and reusable nuts and bolts. The expanded configuration supports ambitious vehicles, structures and mechanical creations for collaborative preschool construction and engineering activities.
EXTRA-LARGE 100 CM WOODEN COMPONENTS
Straight construction boards extend up to 100 cm long with a substantial 2.5 cm thickness. The oversized format moves construction beyond tabletop play, allowing children to create large floor-based structures while exploring proportion, balance and spatial relationships.
620 REUSABLE NUTS & BOLTS
The set includes 310 large ABS bolts and 310 matching nuts for repeated assembling, tightening, adjusting and rebuilding. Children can physically experiment with structural connections while developing coordination, construction planning and early mechanical problem-solving skills.
BUILT FOR GROUP STEAM PROJECTS
With twice the component volume of the 450-piece version, this expanded set supports larger group projects and multiple simultaneous constructions. Wheels, pulleys, ropes, curved boards and connectors encourage teamwork, engineering exploration and open-ended collaborative building.
