There is no issue with the quality of our grass; it has the same density. I have already asked the factory We have sold a lot of this product. I told you that we have no profit from your order, friend. We won't send cheap goods that cause disputes and conflicts; this is not beneficial for our business. You don't need the color of our grass; we agreed to refund and return at very first you told me the problem. Since your sample was bought from a former colleague, we didn't emphasize the grass color with the factory. This may result in the factory sending the wrong color. The color I am sorry for that, but the quality is the same, I am sure about it. We never sell cheap grass. Thanks,friend.
