Assembly Instructions
The LEGO Christmas Tree set offers two primary building configurations:
- Option 1: One Large Christmas Tree Model
Follow the instructions provided in the booklet to construct a single, taller Christmas tree. This model features multiple layers of green bricks, adorned with various colorful ornaments, candles, and a yellow star on top. - Option 2: Two Smaller Christmas Tree Models
Alternatively, you can use the same pieces to build two distinct, smaller Christmas trees. Each smaller tree will have its own base and decorations, allowing for versatile display options.
Refer to the included instruction booklet for step-by-step visual guides for both building options. Ensure all pieces are securely connected to maintain the model's stability.

Display Options
Once assembled, your LEGO Christmas Tree serves as a decorative item. It can be displayed in various settings:
- As a centerpiece on a table.
- On a shelf or mantelpiece.
- In a bedroom or office as festive decor.
The larger tree stands approximately 11 inches (30 cm) tall. The two smaller models stand approximately 9 inches (23 cm) and 6 inches (16 cm) tall, respectively.

Care and Maintenance
To maintain the appearance and integrity of your LEGO Christmas Tree:
- Cleaning: Dust regularly with a soft, dry cloth or a soft brush. For deeper cleaning, gently wash individual bricks with mild soap and lukewarm water (not exceeding 104°F / 40°C). Rinse thoroughly and air dry. Avoid harsh chemicals or abrasive materials.
- Storage: When not on display, disassemble the model and store the bricks in a clean, dry container away from direct sunlight and extreme temperatures to prevent discoloration or warping.
- Handling: Handle the assembled model with care, especially when moving it, to prevent pieces from detaching.
Troubleshooting
- Missing Pieces: If you find any pieces missing from your set, please contact LEGO Customer Service directly through their official website. They have a dedicated service for replacing missing or broken elements.
- Model Instability: Ensure all bricks are firmly pressed together according to the instructions. If a section feels loose, re-examine the corresponding steps in the instruction booklet to confirm correct assembly.
- Difficulty Connecting Bricks: Some new bricks may require a bit more pressure to connect initially. Ensure proper alignment before applying force.
