335-PIECE LARGE MECHANICAL BUILDING SYSTEM
A comprehensive 335-piece construction system combines large plywood structural components with reusable nuts, bolts and mechanical accessories. Children can design vehicles, frames, machines and imaginative structures while exploring connection, movement, spatial relationships and collaborative engineering concepts.
EXTRA-LONG COMPONENTS UP TO 132 CM
Six-hole construction boards reach 132 cm long with a substantial 2.5 cm thickness, supporting large floor-based structures rather than small tabletop models. Different board lengths help children explore scale, span, proportion, balance and structural planning.
BOLTS โข PULLEYS โข ROPES โข WHEELS
Large ABS nuts and bolts combine with wheels, pulleys, ropes, buckets and hooks to extend construction into mechanical experimentation. Children can connect, adjust and rebuild structures while exploring movement, lifting concepts and different ways components work together.
STORAGE CART INCLUDED
The complete configuration includes a 100 ร 60 ร 40 cm storage cart for organizing the large construction components between activities. This makes the expanded mechanical system easier to manage in preschools, kindergartens and dedicated construction areas.
