The tube is designed for convenient storage and transport, making it ideal for travel. After use, store the pieces back in the tube to keep them organized and prevent loss.
4. Operating Instructions
Plus-Plus pieces connect in various ways to create both flat (2D) and three-dimensional (3D) designs. The basic principle involves interlocking the 'plus' shapes.
4.1 Basic Connection
- Hold two Plus-Plus pieces.
- Align the 'plus' shape of one piece with the open space of another.
- Gently push them together until they interlock securely.
4.2 Building the Dolphin Model
This set is specifically designed to build a dolphin. While specific step-by-step instructions for the dolphin model are typically included within the product packaging, the general approach involves:
- Start with a base structure, often forming the body or a central part of the design.
- Gradually add pieces, building outwards and upwards to create the desired shape.
- Utilize the different shades of blue and black pieces to add detail and depth to your dolphin.
- Experiment with piece orientation to achieve curves and specific features like fins and tail.

4.3 Creative Building
Beyond the dolphin, Plus-Plus encourages free-form construction. Users can create:
- 2D Designs: Lay pieces flat to create mosaics or pixel art.
- 3D Structures: Build complex shapes, animals, vehicles, or abstract sculptures.
There are no predefined rules, allowing for complete creative freedom.
5. Maintenance
To ensure the longevity and hygiene of your Plus-Plus pieces:
- Cleaning: Plus-Plus pieces can be washed in a washing machine or dishwasher. Place them in a laundry bag to prevent loss and wash at temperatures up to 90 degrees Celsius (194 degrees Fahrenheit).
- Storage: Store pieces in the provided tube or another suitable container to keep them clean and prevent them from getting lost.
- Inspection: Periodically inspect pieces for any damage. Discard any broken or heavily worn pieces to maintain safety.
6. Troubleshooting
Plus-Plus building sets are designed for straightforward use. No specific troubleshooting steps are typically required for this product.
