GET IN HERE TO KNOW THE MEANING OF THE STRIPES UNDERNEATH YOUR TOOTHPASTES.

 Many of us use toothpastes and we don't even know their composition, although you can't know the composition just by checking the stripes it's better you read the ingredient
The theory is that:

• Green means a completely natural toothpaste
• Blue means the toothpaste’s composition is natural in combination with medicines
• Red means natural plus chemicals
• Black equals all chemicals

But before you go rushing to the bathroom cabinet to throw away your ‘toxic’ toothpaste, here’s the truth.
The squares are actually just part of the manufacturing process, and are called “eye marks.”
The hidden information in these coloured squares are read by light beam sensors and literally just tell the high-speed machinery where the packaging needs to be cut and folded.
