Introduction
This manual provides detailed instructions for assembling the KAWADA Nanoblock Hamburger Building Kit, model NBC217. Nanoblocks are micro-sized building blocks designed for a challenging and detailed construction experience. This kit allows you to create a miniature hamburger model with precision and authenticity.
The kit contains 124 pieces, enabling the construction of a hamburger featuring a patty, cheese, lettuce, and tomato. The small size of the bricks (as small as 4mmx5mm) requires careful handling and contributes to the intricate detail of the final model. This activity helps develop logical thinking, problem-solving skills, and fine motor skills.

Setup
- Unpack Components: Carefully open the product packaging and remove all building block bags and the instruction sheet.
- Organize Pieces: It is recommended to sort the nanoblock pieces by color or shape before beginning assembly. Due to their small size, organizing them can significantly aid the building process.
- Prepare Workspace: Ensure you have a clean, well-lit, and stable surface to work on. This will prevent loss of small pieces and provide a comfortable building environment.
Assembly Instructions
Follow the step-by-step instructions provided in the included instruction sheet. Each step illustrates the placement of specific blocks to construct the hamburger model.
- Refer to Diagrams: Pay close attention to the diagrams in the instruction sheet. They show the exact position and orientation for each block.
- Connect Blocks Securely: Nanoblocks are designed for a secure fit. Ensure each block is firmly pressed into place to prevent the model from falling apart.
- Layer by Layer: The assembly typically progresses layer by layer, building the base of the hamburger first, then adding the patty, cheese, lettuce, tomato, and finally the top bun.
- Patience is Key: Due to the small size of the blocks and the intricate design, assembly requires patience and precision. Take your time with each step.

Care and Storage
- Cleaning: To clean the assembled model, gently wipe it with a dry, soft cloth. Avoid using water or chemical cleaners, as these may damage the plastic or loosen connections.
- Storage: Store the assembled model or unbuilt pieces in a cool, dry place away from direct sunlight and extreme temperatures. Keep small pieces in a sealed container to prevent loss.
- Handling: Handle the assembled model with care to avoid accidental disassembly due to the small, interlocking nature of the blocks.
Troubleshooting
- Missing Pieces: Double-check the packaging and your workspace thoroughly. Due to their small size, pieces can be easily overlooked. If pieces are genuinely missing, contact the manufacturer's support.
- Difficulty Connecting Blocks: Ensure blocks are correctly aligned before applying gentle, firm pressure. Avoid forcing blocks, as this can cause damage.
- Model Instability: Review previous steps in the instruction manual to ensure all blocks are correctly placed and securely connected. A loose connection can affect the overall stability.
