Before the machine is shipped, please contact our staff in time and ask them to take video and photos of the machine inspection. After receiving the goods, open the package immediately and check whether there are any missing parts on the left and right machines. If there are any, please contact our sales staff in time. During the subsequent use of the machine, if some screws or other accessories fall off, you can also contact our staff. As shown in the picture, the accessories we provide to our customers are delivered to the customers by sea freight.
