## Overlaps & pitfalls
- **Overlap:** A plastic sticker with 3D features could fit both 3919.90 and 7117.90. The 3D feature is the deciding factor.
- **Pitfall:** "Sticker" in 4821.90 refers to a stencil, not a permanent decoration—misleading if not clarified.
- **Priority:** Use the product’s **main function**—if it stays on nails as decoration, prioritize permanence and material; if used only as a guide, choose 4821.90
