- Can you customize the samples style according to my design requirement?
Of course! We can customize the process according to your needs: shape cutting, AR AG coating, high temperature oven, polishing and tempering, anti-UV ink printing, based on our mature supply system for processing and customization
- Can I get a sample with my own logo?
Since customized samples and shipping costs are high for both parties, in order to ensure a win-win situation for both parties and quality assurance, we only provide high-quality samples. But we can also provide existing product renderings and design mold services. Usually, we will first provide product renderings with your LOGO as a reference. Click to learn more about free samples
- What is your Production MOQ?
The minimum order quantity for our factory production is flexible and negotiable. Usually the MOQ is 100 pieces, and lower quantity is acceptable for trial order. Please feel free to let us know the quantity you need.
