Find 10 Direct China Factories for Custom Logo-Printed Accessory Packaging Boxes

We are looking for an experienced sourcing agent to find 10 reliable DIRECT FACTORIES in China that can produce custom packaging boxes (with our printed logo) for accessories such as jewelry, watches, and similar small items. This is NOT a design job. We already have our logo and concept. We need you to research, contact, and shortlist real manufacturers and compile their details into a clear comparison spreadsheet. == MOST IMPORTANT REQUIREMENTS == When selecting factories, please prioritize the following: 1. DIRECT FACTORIES ONLY - manufacturers, not trading companies or agents/middlemen. 2. Able to ship directly to JAPAN without going through a trading company or agent. 3. High quality / strong craftsmanship (good print quality and finishing). 4. Fast and responsive communication. == INFORMATION WE NEED FROM EACH FACTORY == For each of the 10 factories, please collect: - Price for 5,000 units AND 10,000 units (per the same box spec) - Shipping cost to Japan for each quantity - Accepted payment methods - Sample lead time AND mass-production lead time - Policy for handling defective products (how they deal with defects/returns) - Factory name, website/Alibaba page (if any), and contact info - A photo or sample image of their work, if possible == DELIVERABLE == Compile all of the above for 10 factories into ONE spreadsheet (Google Sheets or Excel). Please SORT the list from best to worst, ranked by a combination of LOWEST PRICE and HIGHEST QUALITY (cheapest + highest quality at the top). == TO APPLY == Please briefly tell us: - Your experience sourcing factories in China (especially packaging/printing). - Whether you can communicate directly with Chinese factories in Chinese. - How quickly you can deliver the completed spreadsheet. Looking forward to working with detail-oriented, fast-communicating sourcing professionals. Thank you!
