Q: How can i get a quotation ?
A: Please send your drawing or the details of your demand to us, then we will quote to you.
A: Generally it will take about 15-30 days because the production process is a long time cycle, but if we have stock of the products you need, then we can ship out once we get the payment.
Q:What about the package?
A:We pack with plastic bubble paper, carton box, then safe wooden box outside, we can control the breakage less than 1%
