This structure stabilizes the construction and withstands forces without the need for nails. Such ingenious craftsmanship is embodied in the playable Luban lock. Legend has it that it was designed by the master craftsman Luban, while another theory suggests Zhuge Liang invented it based on Bagua metaphysics, hence the Luban lock is also known as the Kongming lock. There are many forms of Luban locks, with the most classic being the "Six Brothers Gathering," a set of six long pieces that interlock via notches and protrusions to form a three-dimensional cross shape. https://live.staticflickr.com/65535/51376178085_f04ecc5997_h.jpg ⚙️ Product Specifications ⚙️ Product Name/Model: Luban Lock / 9AB02201 Package Dimensions: 30.5cm x 13.5cm x 2cm Recommended Age: All ages Challenge Difficulty: ★★★☆☆ Material: Safe and non-toxic plastic Origin: Taiwan ⚠️ Important Notes - Please be mindful of small parts and prevent children from swallowing them. - If any parts are missing or if you have assembly questions, please contact the design hall. - This design hall offers a 7-day appreciation period.
