Key Differences Between YY Lash Types
Base Width & Fan Spread Comparison
The base width determines how easily each type adheres to natural lashes:

| Kitten YY | Slightly Wider Upper Split | Wide Fan | High Volume |
| Narrow YY | Compact U-shape | Tight Fan | Light Volume |

- Narrow: Softer enhancement mimicking natural growth patterns.
