★Delivery Issues: Our store guarantees that all goods are in their original packaging and have been carefully packaged for you. Therefore, we strongly advise: once the buyer receives the items, they must inspect them thoroughly in front of the courier before signing for delivery! First, check whether the packaging is intact, there are no signs of opening, and all related accessories are present. If any discrepancy is found, please refuse to sign the delivery and notify us immediately. If damage or damage to the product is discovered after signing for delivery, the buyer will be responsible for all consequences! Our profit margin is very low, and we cannot afford any unreasonable issues!! Thank you for your cooperation!

★After-sales service: All products in this store are covered by original warranty (free one-year warranty under normal circumstances, not due to human error). Imported brand items can be supported for joint warranty or sent directly back to the store for warranty. If there is a quality issue, a replacement can be provided within seven days of delivery (based on the signed receipt). Damages caused by previous use, machine operation, customer error, or other human factors will not be eligible for return or exchange. If no quality issues are reported within seven days after receipt, it is considered accepted, and any further return or exchange requests will not be accepted.
