How do you guarantee product quality?

We ensure quality by producing a pre-production sample before mass production and conducting a final inspection before shipment. We also perform random visual and function inspections on finished products.

What is the typical lead time for orders?

The lead time depends on the season. During the off-season, it is within 15 workdays. During the peak season, it takes approximately one month.
