Referring to the conventional after-sales rules of the industry and the brand's quality assurance system, there are clear guidelines for after-sales handling.

• Quality problems: If the buttons have non-human-induced quality issues such as cracking or fading, consumers can contact the supplier for return or exchange with the purchase voucher, and the round-trip freight is usually borne by the supplier.
• Non-quality problems: For return or exchange due to subjective reasons such as color and style, the products must be unused with intact packaging, and the round-trip freight shall be borne by the consumer.
• Guarantee basis: With multiple international quality certifications, the brand has strict product quality control, so the probability of quality problems is relatively low.
