80-PIECE NATURAL HOLLOW CONSTRUCTION SYSTEM
This 80-piece construction set combines 64 hollow wooden building components with 16 structural boards. Rectangular frames, arches, semicircles and triangles create open architectural forms, while short and extra-long boards expand construction into bridges, platforms, façades and connected structures.


NATURAL NEW ZEALAND PINE FINISH
The Natural Finish version highlights the lighter tone and visible grain of New Zealand pine rather than a carbonized appearance. A clear water-based finish preserves the natural wood aesthetic while rounded-edge processing and smooth surfaces support a clean preschool construction environment.
OPEN-FRAME ARCHITECTURAL BUILDING
Hollow blocks introduce openings directly into the construction process. Children can combine frames, arches and geometric forms into windows, gateways, towers and building façades while exploring how open space, support, balance and proportion influence larger three-dimensional structures.


STRUCTURAL BOARDS UP TO 120 CM
Twelve short boards and four extra-long 120 cm boards connect and extend hollow structures horizontally. These components can support bridges, platforms, roof-like spans and multi-zone constructions, adding another scale of spatial planning to the open-frame building system.

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 80-Piece Outdoor Hollow Wooden Blocks – Natural Finish?
A: The complete configuration contains 80 components across 12 different component types.
Q: How many hollow structural blocks are included?
A: The set contains 64 hollow structural blocks plus 16 wooden boards.
Q: What material are the blocks made from?
A: According to the supplied specification, the components are made from New Zealand pine with a natural clear water-based finish.
Q: Are these blocks carbonized?
A: No. This version retains the natural wood appearance of New Zealand pine rather than using the darker carbonized finish.
Q: What is the longest component?
A: The longest structural boards measure 120 × 15 × 2 cm.
Q: How many 120 cm boards are included?
A: Four extra-long 120 cm boards are included.


Q: How do hollow blocks differ from conventional solid blocks?
A: Hollow components introduce openings and frame-like forms directly into construction, creating opportunities to build windows, gateways, facades, towers and other architectural structures.
Q: What can children build with the set?
A: The components can be rearranged into towers, bridges, frames, gateways, platforms, façades and other open-ended architectural structures.
Q: Is this a fixed-model construction set?
A: No. The hollow blocks and boards can be repeatedly rearranged into different structures and layouts.
Q: Does the set support STEM exploration?
A: Construction activities provide opportunities to explore geometry, balance, span, scale, symmetry, spatial relationships and basic structural concepts.
Q: How are the accessible surfaces processed?
A: The supplied manufacturing specification requires rounded-edge processing and smooth external, internal and accessible concealed surfaces without burrs or exposed sharp hardware points.
Q: Where can this set be used?
A: It is designed for supervised preschool, kindergarten, outdoor classroom and large-scale construction-play environments.
