A: As mentioned above, since our raw material cost is already the best choice, secondly, we strictly control the production process, strictly control the product quality, and comply with each product process, so the production cost is relatively higher. We dare to promise that our offer is not the lowest on the market, but we can guarantee that our products and prices are the most suitable. Because our quality can meet it compared to the higher end customer demand, and has a relatively low price, our products and prices are only a little higher than their customers who are not demanding quality.
