捷克采购需求：产品，拉链袋

I am interested in ordering 500 pieces of high-quality zipper bags that feature a matte CPE finish. The bags will be customized with my design, which includes a simple white logo that I want printed on a black background. The dimensions I'm looking for are 300x400 mm. Could you please provide me with your pricing details, lead times, and any minimum order requirements? I prefer to handle this communication via email for convenience. Looking forward to your prompt response!
