450-PIECE LARGE CONSTRUCTION SYSTEM
A substantial 450-piece building system combines carbonized New Zealand pine components with reusable nuts, bolts, wheels and mechanical accessories. Children can create large vehicles, frames and imaginative structures while exploring spatial relationships, engineering concepts and collaborative problem-solving.
DISTINCTIVE CARBONIZED WOOD FINISH
New Zealand pine components receive a carbonized treatment followed by an eco-friendly water-based finish, creating a warm, distinctive wood appearance while preserving the natural visual character of the material for classroom construction environments.
EXTRA-LARGE 100 CM COMPONENTS
Straight construction boards extend up to 100 cm long with a substantial 2.5 cm thickness, allowing children to move beyond tabletop models and create large floor-based structures while exploring scale, proportion, span and structural relationships.
MECHANICAL & COLLABORATIVE STEAM PLAY
Large reusable nuts and bolts combine with wheels, pulleys, ropes, buckets and ABS corner connectors to support mechanical experiments and group projects. Children can plan, connect, test, adjust and rebuild structures through open-ended engineering activities.
