227-PIECE INTERLOCKING CONSTRUCTION SYSTEM
This 227-piece construction set combines 11 types of wooden structural components with a paper activity-card set. Posts, slotted pieces, cross connectors, eaves and serrated beams can be assembled in multiple directions, supporting large architectural structures and open-ended preschool building projects.


MORTISE & TENON-INSPIRED CONNECTION PLAY
Unlike conventional stacking blocks, this system emphasizes fitting, inserting, crossing and connecting components. Different openings and notched profiles allow children to investigate how parts join together while creating frames, gateways, elevated structures and increasingly complex three-dimensional constructions.
CARBONIZED NEW ZEALAND PINE
The wooden components are made from New Zealand pine with a carbonized finish and water-based coating according to the supplied specification. Rounded-edge processing, smooth surfaces and burr-free finishing create a consistent construction system with a distinctive warm wood appearance.


BUILD LARGE ARCHITECTURAL STRUCTURES
Long serrated beams reach up to 77.5 cm, while large and small eave pieces add recognizable architectural forms. Combined with multi-mortise posts and connector blocks, the system supports gateways, towers, frames, elevated platforms and imaginative large-scale structures.

Q: How many pieces are included in the 227-Piece Outdoor Mortise & Tenon Building Set?
A: The supplied configuration contains 226 wooden construction components plus one paper activity-card set containing 10 sheets, listed as 227 pieces per set.
Q: How many wooden component types are included?
A: The construction system contains 11 wooden component types.
Q: What material are the wooden components made from?
A: According to the supplied specification, the components are made from New Zealand pine with a carbonized finish.
Q: What is the largest component?
A: The detailed configuration lists the longest serrated beam at 77.5 ร 7.5 ร 3.75 cm.
Q: What is special about the construction method?
A: Unlike conventional stacking blocks, the system uses slotted, notched and interlocking components that provide opportunities to explore inserting, crossing, connecting and extending structural elements.
Q: Does the set include mortise-style posts?
A: Yes. Fifty multi-mortise post components measuring 37.5 ร 7.5 ร 3.75 cm are included.


Q: Are different beam lengths included?
A: Yes. Four single-sided serrated beam lengths are included: 34.5 cm, 49.5 cm, 64.5 cm and 77.5 cm.
Q: What finishing process is used?
A: The supplied manufacturing information specifies carbonized treatment, water-based finishing, rounded edges, smooth surfaces and burr-free processing.
Q: What can children build with the set?
A: The open-ended components can be combined into gateways, towers, frames, elevated structures and other imaginative architectural constructions.
Q: Is this a fixed-model building kit?
A: No. The components can be recombined in multiple ways for open-ended structural construction.
Q: Does the set support STEM exploration?
A: Construction activities provide opportunities to investigate connections, structure, stability, spatial relationships, sequencing and practical engineering concepts.
Q: Where can the set be used?
A: It is designed for supervised preschool, kindergarten, outdoor classroom and large-scale construction-play environments.
