Professional and productive communication. My contact Calthy asked the right questions and provided product details, photo's, technical drawings and even a video of the production of the first samples. My product specifications are read and translated into technical drawings very well. Provided details in the drawings are in Chinese, I had to translate it myself. The samples were produced and sent within a week, received the week after. Product quality and properties meet all my specifications or are in line with what was communicated by my contact beforehand. This is my preferred supplier now.
