Q1: How about MOQ?
MOQ is according to different products. Whatever you need, we are glad to quote best price with good quality.
Q2: Can you send samples for testing?
500g Samples are free supplied, but express freight should be taken by client. After making order, we’d like to return freight back.
Q3: How can you guarantee the quality of mass goods is same as the sample sent to me before?We kept another same sample and marked on company when we sent to customer. So our production will be based on.
Q4: Which package do you use?
Package is important part to avoid goods breaking in transportation. We will choose suitable packing depend on materials.Q5: When customer respond quality issues after pick up goods, how to deal with?
1) Customer could supply photos of issued goods for our sales staff and then we’ll verify which part is wrong.
2) If the issue is confirmed, company will negotiate with customers and compensate in coming orders.
