Fast Response -
I contacted Lili Chen of Qingdao Heli Fiber Co. Ltd and I inquired about their Elastic yarn (20/70). I received a response from her immediately after I sent the inquiry which was very prompt. In terms of pricing, their product is one of the cheapest that I could find and payment terms are pretty flexible compared to others. Although lead time to send the product and warranty terms were not mentioned, I would still commend Lili for providing detailed information to most of my questions.
It would be nice to visit their factory to check the quality of their products in person but I would definitely consider their company to my supplier list because of their fast and direct approach, and the competitiveness of their price.
