Photo Review of Colgate Cavity Protection Toothpaste 180g

This is the Colgate toothpaste cool mint flavour. I aware that there is a blue mark at the end of the toothpaste. Actually it’s a manufacturing mark, called an eye mark or color mark. These marks are used by automated machines in factories to detect where to cut, seal, or fold the tube or packaging. The color line has nothing to do with the chemical content, naturalness, or safety of the toothpaste — it’s purely for packaging alignment during production.
