Wait a few weeks before selling brand names again but, as a rule of thumb...
You always interview your DHGate seller front to back, make sure they have a powerseller rating or so of about 30.
Make certain the product comes with original certificates. Original box and warranty.
And is in top condition. When those three things are satisfied, you won't get into trouble.
Except at a time like right now, because trademark owners are everywhere at the moment. They report anyone to VERO and its best to avoid brand products right now.
