FAQ
Q1: Can I have a sample for testing?
A: Yes! The test can intuitively show the application result. Actually, the sample is free;
you just need to pay for the express cost.
Q2: Can I use our packing?
A: Yes! OEM is available for us. You can send your packing material to our factory
or we can purchase the designated packing for you.
You may pay for some extra cost if caused.
Q3: Do you have inspection procedures for evaporation materials?
A: 100% self-inspection before packing
Q4: What's my consideration when I choose one kind of evaporation material?
A: The application and the application effect you want.
