    FAQ


    Q1: Do you provide samples ? is it free or extra?

    Pakheng: Yes, normally we could offer the sample for free charge but do not pay the cost of freight.

      

    Q2: How long is your delivery time?

    Pakheng: Generally it is 1-2 working days if the goods are in stock. Or it is 7-10 days if the goods are not in stock, it is according to quantity.

      

    Q3: Is it OK to print my logo on the packing?

    Pakheng: Of course, customized packing accepted!! But it may bring some cost, it depends on the qty and the packing. 

     

    Q4: What is your terms of payment ?

    Pakheng: Full 100% payment before delivery.

      

    Q5: How do you guarantee my goods right?

    Pakheng: Order will be arranged exactly as requested, we will doubly check the packing and qty before delivering out also we will take you photos if required or necessary.
