There is no guarantee for buying things on Alibaba, and the quality is poor. I bought 150 brushes, but one was missing and the other 6 were all broken. I asked for a refund for 7 but the seller disagreed. I gave a bad review, but it was not shown at all. The refund was very small, only 8.89 yuan. It was not for the money. I wanted to teach the seller a lesson, and then applied for after-sales service, but the seller refused. Then I complained, and the seller agreed to refund 0.01 yuan, and then the complaint channel was automatically closed, and I could not complain anymore. I want to tell everyone, don't buy things on Alibaba, I'd rather go to Taobao, where after-sales service is guaranteed
