Hello, there are many coasters. Paper cup coasters need to apply for category 16, non-paper cup non-textile coasters need to apply for category 21, and textile coasters need to register for category 24. These are all related to coasters. Relatedly, if you want comprehensive protection, try to apply for protection in all categories. In addition, you can also apply for protection in 35 categories. Category 35 is advertising and website promotion. It seems that you must have 35 categories of trademarks to enter Tmall Supermarket. I hope my answer is right for you. It's helpful and I hope you can adopt it. Thank you. If you have more questions in this regard, feel free to ask me.
