The Nanoblock NBH-192 model is assembled manually by connecting the micro-sized building blocks according to the included detailed instruction booklet. Follow these general guidelines:
- Step-by-Step: Proceed through the instruction booklet one step at a time. Each step typically adds a small number of blocks to the structure.
- Precision: Due to the micro size of the blocks, precision is key. Ensure each block is firmly seated and aligned correctly before moving to the next step.

6. Maintenance
To ensure the longevity and appearance of your assembled Nanoblock model:
- Cleaning: Use a soft, dry brush or a can of compressed air to gently remove dust from the model. Avoid using water or chemical cleaners, as these may damage the plastic.

- Disassembly: If you choose to disassemble the model, do so carefully to avoid breaking or losing blocks. Store blocks in a sealed container.

If you encounter difficulties during assembly, consider the following:
- Missing Pieces: Double-check your workspace and the packaging. Due to their small size, blocks can be easily overlooked. If a piece is genuinely missing, contact KAWADA customer support.
- Difficulty Connecting Blocks: Ensure blocks are oriented correctly. Apply gentle, even pressure. Avoid excessive force, which can damage the blocks.
