Setup and Assembly
The JEKCA building system uses a patented locking technology to create durable sculptures. Follow the detailed step-by-step manual included in your package for precise assembly.
Key Assembly Principle: Locking Mechanism
Unlike traditional building blocks, JEKCA models are secured using pins and a pin driver. This method ensures the structure remains stable and does not easily fall apart.

Image Description: An illustration demonstrating the JEKCA locking mechanism. It shows a green pin being inserted into a block, followed by a screwdriver turning the pin 90 degrees to secure the blocks together. Text labels indicate "1. Insert screw" and "2. Turn 90°", highlighting the simplicity and sturdiness of the system.
Each step in the physical instruction manual will guide you on where to place each brick and how to use the pins and pin driver to secure them. Pay close attention to the orientation of the bricks and the direction of the pins for optimal stability.
