3. Features and Protection

The USTIYA Clear TPU Protective Case is engineered to provide reliable protection while maintaining the phone's original aesthetic.

• Shock Absorption: The case features a padded silicone body and reinforced four corners designed to absorb and disperse impact forces from accidental drops.
• Scratch Resistance: The durable TPU material helps protect the phone's back and sides from scratches and abrasions during daily use.
• Anti-Yellowing Design: The internal micro-dot pattern is specifically designed to prevent the common 'wet' or 'sticky' appearance and reduce discoloration over time, preserving the case's transparency.
• Screen and Camera Protection: Raised edges around the screen and camera module ensure that these vulnerable areas do not make direct contact with flat surfaces when the phone is placed down.

4. Maintenance

To ensure the longevity and clarity of your USTIYA Clear TPU Protective Case, follow these simple maintenance guidelines:

• Cleaning: Regularly wipe the case with a soft, damp cloth to remove dust, fingerprints, and smudges. For more stubborn dirt, a small amount of mild soap can be used, followed by rinsing with water and air drying.
• Avoid Harsh Chemicals: Do not use abrasive cleaners, alcohol, or strong chemical solvents, as these can damage the TPU material and affect its transparency.
• Storage: When not in use, store the case in a cool, dry place away from direct sunlight to prevent material degradation.

5. Troubleshooting

This section addresses common inquiries regarding the protective case.

5.1 Case Discoloration Over Time

While the case is designed with anti-yellowing properties (micro-dots), all transparent TPU materials may exhibit some degree of discoloration over extended periods due to UV exposure and environmental factors. Regular cleaning as described in Section 4 can help maintain its appearance. If significant discoloration occurs, it is part of the natural aging process of the material.

5.2 Case Does Not Fit My Phone

Ensure that your phone model is specifically listed as compatible: Vivo Y20, Vivo Y20S, or Vivo Y11s. This case is precisely molded for these models. If your phone is a different model, the case will not fit correctly. Verify your phone's model number in its settings.
