How does your factory control quality?

Quality is at the forefront of our commitments. We have a strict process: Material Vendor Assessed, Incoming material inspected (IQC), In-line product 100% Check (QC), 100% inspect before packing (QC), and random checks after final packing (QA).

Normally we take the order no matter if it's big or small. If your qty is less than 5pcs per SKU, we will arrange it in our sample room specially.

Can I make my own brand?

Yes, we do both OEM and ODM, so you can make your own logo on the bags.
