4. Assembly Instructions
The Nanoblock Cinnamoroll model has a difficulty level of 2 out of 5. Follow the included instruction sheet for precise step-by-step guidance. The general process involves:
- Preparation: Open the package and carefully sort the Nanoblock pieces by color and shape. This will make the assembly process smoother.
- Base Construction: Begin by building the base structure of Cinnamoroll, typically starting from the bottom up. Refer to the instruction sheet for the exact starting point.
- Layer by Layer: Nanoblock models are built layer by layer. Each step in the instruction sheet will show which blocks to add to the current layer. Pay close attention to the orientation and placement of each block.
- Detailing: As you progress, you will add smaller details such as Cinnamoroll's ears, facial features, and tail. These often use the smallest blocks.
- Completion: Continue until all pieces are used and the model matches the image on the packaging and in the instructions.

5. Care and Maintenance
To ensure the longevity and appearance of your Nanoblock model:
- Cleaning: Gently dust the model with a soft brush or a can of compressed air. For stubborn dirt, lightly dampen a cloth with water and wipe carefully. 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, especially when moving it, to prevent pieces from detaching.
6. Troubleshooting
- Missing Pieces:
- Carefully re-check the packaging and your workspace. Due to the small size, pieces can be easily overlooked. If a piece is genuinely missing, contact customer support.
- Difficulty Connecting Blocks:
- Ensure blocks are correctly aligned and pressed firmly. Sometimes a slight twist can help. Do not force blocks, as this may cause damage.
- Model Instability:
- Review previous steps in the instruction manual to ensure all blocks are placed correctly and securely. An incorrectly placed block can affect the stability of subsequent layers.
