569-PIECE INTERLOCKING CONSTRUCTION SYSTEM
This 569-piece outdoor construction set combines multi-hole wooden blocks with six sizes of connecting rods, allowing structures to be joined rather than simply stacked. The system supports large-scale building, mechanical thinking and more complex three-dimensional preschool construction.


380 MULTI-HOLE WOODEN BUILDING BLOCKS
Twenty-five structural block formats provide 380 wooden components, including long perforated boards, solid bricks, cubes, triangles, cylinders, circles and semicircular forms. Different hole arrangements create multiple connection points for experimenting with direction, height, span and structural combinations.
180 CONNECTOR RODS IN SIX LENGTHS
Six connector-rod sizes ranging from 5 cm to 30 cm provide 180 reusable connecting components. Children can select different lengths to join blocks, create spacing between structures and explore how connection position and distance affect the final construction.


ENGINEERING PLAY WITH VEHICLES & CARTS
Six themed wooden vehicles and three larger carbonized carts extend construction into transportation and imaginative engineering scenarios. Roads, garages, bridges, stations and connected structures can be incorporated into larger collaborative building environments.

Compliance & Safety All our educational toys strictly comply with international safety standards, including EN71 (Europe), ASTM F963 (USA), and CPC (Children’s Product Certificate). We use only 100% non-toxic, BPA-free materials and eco-friendly water-based paints. Full laboratory testing reports are available upon request for authorized distributors.
Q: How many pieces are included in the 569-Piece Outdoor Interlocking Building Block Set?
A: The complete supplied configuration contains 569 pieces.
Q: How many multi-hole wooden building blocks are included?
A: The structural block portion contains 380 multi-hole wooden components across 25 block formats.
Q: How many connector rods are included?
A: The set contains 180 connector rods across six lengths from 5 cm to 30 cm.
Q: What material are the main building blocks made from?
A: According to the supplied specification, the wooden components are made from New Zealand pine with carbonized treatment and a water-based finish.
Q: What is the longest building component?
A: The longest perforated wooden board measures 120 × 10 × 2.5 cm and contains 12 connection holes.
Q: How does this set differ from conventional wooden building blocks?
A: In addition to stacking and balancing, the multi-hole components can be joined with connector rods, allowing children to explore more complex three-dimensional structures and connection-based construction.


Q: How many connector sizes are included?
A: Six lengths are included: 5 cm, 10 cm, 15 cm, 20 cm, 25 cm and 30 cm.
Q: What can children build with this system?
A: The components can be connected into towers, bridges, frames, roads, garages, stations, vehicles and other open-ended engineering structures.
Q: Is this a fixed-model construction kit?
A: No. The blocks and connectors can be repeatedly rearranged into different structures and layouts.
Q: Does this set support STEM exploration?
A: The connector-based construction system provides opportunities to explore geometry, length, spacing, structure, connection points, stability and practical engineering concepts.
Q: Does the set support collaborative construction?
A: The 569-piece configuration provides opportunities for supervised collaborative and small-group engineering projects.
Q: What finishing process is used?
A: The supplied specification describes carbonized treatment, water-based finishing, rounded-edge processing and smooth, burr-free surfaces.
