Visit Us

Come See It in Person — or on a Live Video Call

Many clients fly in for a one-day audit: a full floor walk-through, sample review in our showroom and a sit-down with the production planners. We are 1 hour from Shenzhen Bao'an airport and can help arrange the visit end to end.

If travel is not on the table, we run live video inspections on WhatsApp or Zoom. You choose the route — printing, lamination, bag-making or QC — and talk directly to the people running the line.

FAQ

Factory Visit FAQ

Can I visit your factory in person?

Yes. We welcome client audits and visits at our 10,103 m² facility in Shenzhen, China. Message us 1–2 weeks ahead and we will arrange the tour, sample review and a meeting with the production team.

Can you do a live video factory inspection instead?

Yes. If travel is not convenient, we run live video walk-throughs on WhatsApp or Zoom — you can inspect the printing, lamination, bag-making and QC areas in real time and ask questions on the spot.

Will I see my own product being made during the tour?

For running orders, yes — you are welcome to watch your own production run and QC checks. For new projects, we combine the tour with free stock samples and a color-matching session.
