What about your after‑sales service?

Every batch of goods will be fully inspected on appearance, dimension and light transmittance before delivery. If mass‑scale quality defects occur after receiving goods, please send us clear photos and video evidence promptly. We will trace root causes quickly. Remedies including rework, replacement or refund will be arranged if defects are caused by our production. Damage from improper human operation or secondary processing after delivery is excluded from after‑sales coverage.
