UNIU is committed to creating products that combine protection, design, and a great everyday user experience.
From material selection and structural design to actual use testing, all products undergo multiple quality inspections and real-world scenario tests to ensure stable performance in various environments.

The structure and special design of some products are also validated by third-party laboratories to provide a more complete product experience and after-sales service.

UNIU provides quality warranty service for designated products. If the product itself experiences functional abnormalities caused by non-human factors under normal use, corresponding after-sales assistance will be provided after confirmation.

The warranty covers:

• Abnormal protective structure
• Abnormal button feedback
• Abnormal magnetic function
• Structural abnormalities
• Functional issues affecting normal use

The warranty period will vary depending on the product type and series; please refer to the product page for actual details.

The following situations are considered normal wear and tear or not product defects, and are therefore not covered by the warranty:

• Cosmetic scratches, abrasion, and signs of use
• Natural yellowing or discoloration of transparent materials
• Damage caused by accidental drops, impacts, or crushing
• Unauthorized disassembly, modification, or improper use
• Deformation or damage caused by exposure to high temperatures or contact with chemicals
• Issues arising from the use of third-party accessories

Different materials may undergo natural changes due to usage habits and environmental factors, which are considered normal wear and tear.
