Does putting a serial number on a counterfeit good increase the penalty if caught? - serial number jx ovulation calendar

I bought razors off eBay, I could not say one way or another if they are true or false. They work well and do not care, but someone told me that, since the cartridges are printed with a serial number on it are probably true, but if you put a fake serial number is one thing that the line of manufacturing products of organized crime (?) or something crosses. Is that true?
