You have to be accurate when you open a case, or you will lose the case.

For example, if something is missing from a parcel it is not an INR case, but an INAD case.

The product has a brand (Rayhong). If you call it fake, it means it is a knock-off of that brand. It does not mean it does not do what it is supposed to do.       

Additionally, if you complain that it is liquid and the title/description says it is liquid, eBay will think that you have not read the description.
