Build Tips
Check the piece count on the bag against the parts list before starting — knowing what you have prevents mid-build surprises.
Even in small sets, connection order matters. Follow the steps rather than building sections independently.
Once built, direct sunlight yellows ABS plastic over time. A display case or UV-filtered shelf glass keeps colors vibrant.
