However, if the customer has some specific requirements such as product size, material, color or LOGO, we shall charge the relevant costs. We are keen for your understanding that we would like to charge the sample cost which will be deducted once the order is confirmed. Once you are satisfied with our sample quality and place an order with required MOQ, we surely return such amount.
