2. Safety Information
- Age Recommendation: This building block set is recommended for ages 8 and up. Some components are very small and are not suitable for children under 6 years old due to choking hazards.
- Material Safety: The building blocks are made from high-quality, non-toxic ABS plastic, ensuring safe play.
- Supervision: Adult supervision is recommended, especially for younger children, to assist with assembly and ensure safe handling of small parts.
- Handling Small Parts: Exercise caution when handling the micro-sized blocks to prevent accidental ingestion or loss.
3. Setup and Assembly
Each animal model is individually packaged with its own instruction manual. Follow the steps outlined in each manual carefully for successful assembly.
General Assembly Tips:
- Organize Parts: Before starting, open the package for the specific animal you wish to build and sort the blocks by color or shape. This will make it easier to locate the necessary pieces.
- Follow Instructions: Refer to the step-by-step diagrams in the included instruction manual for each model. Pay close attention to the orientation and placement of each block.
- Secure Connections: Ensure each block is firmly pressed into place to create a stable structure. Micro blocks require precise alignment.
- Patience is Key: Due to the small size of the blocks, assembly may require patience and fine motor skills. If a piece is difficult to connect, try adjusting its angle or using the included brick tool if available.
- Eye Placement: Some users have noted that the eye pieces may not always stay firmly in place. Ensure they are pressed securely. If persistent, a tiny drop of non-toxic, quick-drying adhesive can be used for permanent attachment, though this is not typically required.

5. Maintenance and Care
To ensure the longevity and cleanliness of your building block models, follow these simple care instructions:
- Cleaning: Gently wipe the assembled models with a soft, damp cloth to remove dust. Avoid using harsh chemicals or abrasive materials.
- Storage: Store unassembled blocks in their original packaging or a secure container to prevent loss of small pieces. Keep assembled models in a clean, dry environment away from direct sunlight to prevent discoloration.
- Avoid Extreme Temperatures: Do not expose the blocks to extreme heat or cold, as this may cause material deformation.
6. Troubleshooting
If you encounter any issues during assembly or play, consider the following:
- Missing Pieces: Double-check all packaging and the surrounding area. Due to the micro size, pieces can be easily overlooked. If a piece is genuinely missing, contact customer support.
- Difficulty Assembling: Ensure you are following the instructions precisely. Sometimes, a slight rotation or different angle is needed for micro blocks to snap together. Refer to the diagrams closely.
- Loose Connections: Press blocks firmly together. If a connection remains loose, verify that the correct pieces are being used as per the instructions.
- Eyes Not Staying On: As mentioned in assembly tips, ensure the eye pieces are pressed in securely. For a more permanent fix, a minimal amount of non-toxic adhesive can be applied.
