Comparison checklist
- Category fit: confirm the factory already works with the bag type you need.
- Sample room: confirm who handles revisions, trim confirmation, and material matching.
- Factory proof: check if the site explains proof routes instead of hiding them.
- QC logic: confirm what happens during inline inspection, final inspection, and shipment release.
- RFQ clarity: check whether the contact path supports proof, sample-development, and direct manufacturing requests.
