I'm new to this site but hoping I will hear from you.
I have come up with an idea - actually have been developing it for about a year now, since I have been the one needing this particular product. It's a very simple cover that I'm considering using for a very specific purpose. The main thing is, this product requires just a sheet and some stitching. I have made the request on Alibaba and got 4 responses. We have done some back and forth about specifications, and based on their machinery capabilities I have specified what I need. The kind of material, size, stitching. Simple as that. I believe that this product would benefit many people; I have done my research with people with similar issues that I have at home, and realized that no one has the answer how to solve this issue - thus my idea, and my willingness to have it produced. But since I'm worried that the manufacturer would steal my idea, I have decided not to disclose the product's purpose, and to have it made just partially in China, and finalize it myself. But one of the four manufacturers keeps asking me what I will use the product for. I have ignored his question three times already, and I'm wasting energy thinking what I should say so they leave me alone and just do the sheet and send me a few samples. This is sort of me asking "cut me a board 2x2, paint it red with outdoor paint, and send me a sample". Are my worries justified? Does the manufacturer really need to know what my product is for?
