Hello i am this business for a few years i am looking for a new supplier as my old one is out of business now, i usually buy 1kg per month , i get lied too many times when i was looking for a new supplier i ask for a sample for testing the quality, they said to send them the sample cost or the shipping cost, i do that for a few times and nothing happen, i lose about 400dollars like that, so now i have a single condition first i need you to send me a sample to test it with no shipping cost please, and then after the test if quality is good i pay you the last freight on my big order, thanks and have a nice day.
