Generally, as long as you buy things in the flagship store, there will be no fake and shoddy products. Flagship stores are officially certified, and everything you sell is certified. Don't be afraid. Of course, if you buy a fake one, it is recommended to find the flagship store customer service to solve it. If you can't solve it, you can directly ask Taobao customer service to intervene.
Flagship stores are generally operated by manufacturers themselves, and the things they sell are checked at different levels. Registration is also a company nature, which is very secure.
