4. Care and Maintenance
To ensure the longevity and effectiveness of your Spigen Rugged Armor case, follow these simple care instructions:
- Cleaning: Wipe the case regularly with a soft, damp cloth to remove dust and fingerprints. Avoid using harsh chemicals or abrasive cleaners, as these can damage the matte finish and material.
