SAGAWIT believes that A SAMPLE IS NOT JUST A SAMPLE.
In China, most of the factories don't take sampling seriously. What you can typically hear from them is
"It is just sample, we can make it right during production" or "We can make it, its just that the sampling schedule is too tight."

based on universal industry standard and your specific requirement, SAGAWITs professional QC will inspect every single sample you select.  A First article inspection form will be generated beforehand with QCs comment on how the sample conforms to the requested specifications, how it works in the mass productions, and other special note that we think is important to be aware of. Finally, names will be found on the lower side of the page so that you know whos accountable for the inspection.
