First of all, our QC no-ticket products are inspected for product quality, size and packaging.

Second: We will leave samples for each shipment, and then put them to the laboratory for testing, including inspection, discoloration, deformation problems due to temperature changes, hardness testing, etc.

Third: We will let customers fill out a feedback form if the shipment is not shipped. A feedback on our quality. Quality is our top priority, and we take it very seriously.
