1. Introduction
Thank you for purchasing the KAWADA nanoblock Polar Bear Building Kit. This kit allows you to construct a detailed micro-sized model of a polar bear using nanoblocks, which are significantly smaller than standard building blocks. This manual provides essential information for assembly, care, and safety to ensure an enjoyable building experience.

2. Safety Information
WARNING: CHOKING HAZARD - Small Parts. This product contains very small parts and is not suitable for children under 3 years of age. Keep all components away from infants and young children to prevent accidental ingestion.
- Recommended age for assembly is 15 years and up due to the small size and intricate nature of the blocks.
- Always build in a well-lit area to avoid eye strain.
- Keep blocks away from pets, as they may mistake them for food.
3. Product Overview
The nanoblock Polar Bear model (NBC_294) is part of the Animals Collection series. When assembled, the model stands approximately 1.4 inches (3.5 cm) tall and consists of 220 individual pieces. The blocks are micro-sized, with the smallest measuring 4mm x 4mm x 5mm, allowing for highly detailed and realistic constructions.

4. Setup
- Unpack Components: Carefully open the product packaging and remove all contents. Ensure that the instruction sheet and all block bags are present.
- Prepare Workspace: Choose a clean, flat, and well-lit surface for assembly. Due to the small size of the blocks, it is recommended to work on a surface where small pieces will not easily roll off or get lost.
- Organize Blocks: If desired, sort the blocks by color or size before beginning assembly. This can help streamline the building process, especially for complex sections.
5. Assembly Instructions
The nanoblock Polar Bear kit includes a detailed, step-by-step instruction sheet. Follow these instructions carefully to assemble your model.
- Follow Step-by-Step Diagrams: Each nanoblock kit comes with visual instructions. Pay close attention to the diagrams, which illustrate block placement for each step.
- Block Orientation: Ensure blocks are oriented correctly as shown in the instructions. Incorrect orientation can affect the stability and appearance of the final model.
- Firm Connections: Press blocks firmly together to ensure a secure connection. This will prevent the model from falling apart during or after assembly.
- Difficulty Level: This model is rated at a Level 3 difficulty (on a scale of 1 to 5, with 5 being most advanced). Patience and attention to detail are key.

6. Maintenance
- Cleaning: To clean your assembled nanoblock model, gently wipe it with a dry, soft cloth. For more stubborn dust, a soft brush or a can of compressed air can be used. Avoid using water or chemical cleaners, as these may damage the blocks or cause discoloration.
- Storage: Store your nanoblock model in a stable location away from direct sunlight, extreme temperatures, and high humidity to prevent warping or fading of the blocks.
- Disassembly: If you wish to disassemble the model, do so carefully to avoid breaking or bending the small connection studs. A block separator tool (not included) can be helpful for this process.
7. Troubleshooting
- Missing Pieces: If you believe you have missing pieces, first double-check the packaging and your workspace. Due to their small size, blocks can be easily overlooked.
- Difficulty with Assembly: If you encounter difficulty, review the instruction diagrams carefully. Sometimes, a slight misplacement in an earlier step can affect subsequent steps. Take a break and return to it with fresh eyes if needed.
- Loose Connections: Ensure blocks are pressed firmly together. If a section feels loose, gently re-press the connected blocks.
