It is understood that if the shape of jewelry is relatively small, printing will affect the beauty of the product or damage the product, so it is not required to do printing identification. So sometimes there may be no logo on the jewelry you buy, but it is very important to choose the brand when buying jewelry. Generally speaking, brand manufacturing enterprises pay special attention to product quality and customer service. If you feel uneasy, it is recommended to go to the local quality inspection department for re-inspection. Personally, I think it is not necessary. Longfeng jewelry is a good brand with a long history. Everyone's eyes are sharp. If you have a bad reputation, there will be no market for a long time. In addition, if you are dissatisfied with their store manager or have difficulty in purchasing, you can go to their company headquarters to complain.
