4. Assembly Instructions
Follow the detailed step-by-step instructions provided in the included booklet to assemble your Izuku Midoriya model. The nanoblock pieces are exceptionally small, measuring as tiny as 4mm x 4mm x 5mm, which allows for incredible detail in the final model.
- Preparation: Lay out all pieces on a clean, flat surface. Organize pieces by color and size if helpful.
- Follow the Booklet: Refer to the instruction booklet for precise placement of each block. The instructions are visual, guiding you through each layer and section of the model.
- Precision: Due to the small size of the blocks, careful handling and precise placement are crucial for a stable and accurate build. A pair of tweezers (not included) may assist with very small pieces.
- Layer by Layer: Most nanoblock models are built layer by layer from the base upwards. Ensure each layer is firmly connected before proceeding to the next.
While the instructions are detailed, some steps may require careful observation of the images to determine exact piece counts and positions. Take your time and enjoy the building process.

5. Care and Maintenance
To ensure the longevity and appearance of your nanoblock model, follow these care guidelines:
- Cleaning: Dust your model regularly with a soft brush or a can of compressed air. For deeper cleaning, gently wipe with a damp cloth and mild soap, then rinse and air dry thoroughly. Avoid harsh chemicals.
- Storage: Store the assembled model in a stable location away from direct sunlight and extreme temperatures to prevent discoloration or material degradation.
- Handling: Handle the model with care to avoid accidental disassembly, especially when moving it.
6. Troubleshooting
If you encounter difficulties during assembly or with your nanoblock kit, consider the following:
- Missing Pieces: Double-check all packaging materials. If pieces are genuinely missing, contact the manufacturer for assistance.
- Difficulty Assembling: Ensure you are following the instruction booklet precisely. Sometimes, a small misplacement can affect subsequent steps. Re-examine the images in the manual carefully. The small size of the blocks can make some connections feel delicate; apply gentle, firm pressure.
- Model Instability: Verify that all blocks are fully pressed together and seated correctly. Loose connections can lead to an unstable model.
