- Storage: Always store unused blades in their original dispenser. The dispenser is designed for safe and convenient storage. Keep the dispenser in a dry place, away from extreme temperatures.
- Disposal: Dull or broken blades should be disposed of responsibly. Place them in a dedicated blade disposal container or a sturdy, puncture-resistant container before discarding with general waste. Do not simply throw loose blades into the trash.

7. Troubleshooting
- Blade not cutting effectively: The blade may be dull. Replace it with a new, sharp blade from the dispenser.
- Blade breaking or chipping: This can occur with excessive force or when cutting very hard materials. Ensure you are using appropriate pressure and technique for the material. Replace the blade if damaged.
- Difficulty removing blades from dispenser: Ensure the protective cover is fully pulled down. If still difficult, use a dull blade or a thin, non-sharp object to gently push a new blade out through the designated slit.
