Our contact Miss Mango Zheng is very helpful and quick to send us a quote and manage everything necessary for the delivery of goods to our warehouse. We have already ordered their products twice and the door-to-door service was amazing. Since we bought caps to Tianjin, we don't have any problem with the quality.

I am very satisfied to do business with Tianjin Rainbow, products and supplier service is excellent. I would like to thank Mango Zheng for her good service, hard work and dedication
