What Customers Are Saying
Good communication and support throughout the process. The bags were delivered as agreed and arrived in good condition at the factory. Communication with Luna was very good; she was always helpful, responsive, and willing to assist with any questions. We are still in the middle of production for our final product, but so far the experience with the bags and the service has been positive. Looking forward to continuing the cooperation.
I’m really happy with the quality of the product,the product has exceeded my expectations, it’s so much better than I thought it would be.
This was our 3rd time ordering from Shenzhen Yongliantai Plastic. They delivered earlier than it was promised. The shipping was exactly as promised. Good quality at the best price.
Highly recommend this company and if you have a chance ask for Iris.
We will definitely do business with SYP again.
