From the search results you can see that their contact information is the same as on their website. They have been in business for over 6 years and they update their info regularly. Another positive is that their email is not on a free hosting account which adds some reputability to their company.
I would still do a sample order though as they have no ratings in the Salehoo directory currently. By placing a small order you can see whether or not their products are satisfactory to your requirements, what their customer service is like and how reliable their shipping is.
Here is their link in the Saleho directory...
