1. Unboxing Video Requirements (Important)

To avoid disputes regarding damage during transit or missing accessories, you must record a complete, uninterrupted unboxing video immediately after receiving the package.

This video will serve as the primary evidence for any after‑sales claims.

Video recording rules:

Show the original condition – Before opening, clearly film all six sides of the package. Ensure the shipping label (tracking number, recipient information) and any visible damage (crushes, punctures, water stains, or signs of resealing) are recorded.

Continuous recording – From the moment you start unsealing until you finish checking all items, keep the camera running without pauses or edits.

Inspect and count each item – Compare with your order. Take out every item and show them clearly in the video. This includes but is not limited to:
