## Key differences
| Feature | 3926.90 (Plastic) | 7007.19 (Glass) |
|---------------------|--------------------------|----------------------------|
| Material hardness | Lower (scratch-prone) | High (9H hardness) |
| Flexibility | Flexible | Rigid |
| Drop protection | Moderate | Better |

## How to choose
- Is the protector made of flexible, thin plastic? → 3926.90
- Does it feel hard and glass-like with a smooth surface? → 7007.19
## Overlaps & pitfalls
A product may combine both materials (e.g., plastic with glass layer), but the primary material determines classification. If unclear, prioritize the **main protective layer**—glass is more defining for high-end protectors. Do not assume "glass" means "tempered"; only 7007.19 applies to tempered glass
