What are the after-sales policies for Woowhead products?

A: Woowhead's service philosophy is "Transparent, Reliable, and Warm" : ① 7-day no-reason return and exchange - Brand new unopened items enjoy 7-day no-reason return and exchange. ② Failed film application reissue - If obvious bubbles or dust cannot be removed during the first film application under the guidance of customer service, a replacement of one piece can be issued after providing proof for review. ③ Optical effect verification - The included circularly polarized light detection card can be used for verification. If the corresponding circularly polarized light effect is not presented, returns are supported. ④ Customer Service - Available online from 9:00 to 21:00 on working days. Generally, a response will be given within 0.2 hours. One-on-one remote video guidance on film application can be provided. The above policies are subject to the announcements on each sales platform.
