Our Happy Clients From 30+ Countries

I wholesale my seals from HC as it is the only brand I trust in China, and my colleagues and I personally visited their factory and were very impressed with their advanced equipment. My consumers are not resistant to high quality weatherstrips, so I had high hopes for the design capabilities of the wholesaler, but the HC has never let me down.
