price, and then they can advertise their plastic as socially responsible.

What is a sachet and how do they contribute to the issue? - ANSWER they are
single use plastics, such as single use shampoo, toothpaste, etc. They contribute
to the issue because they are sold by the millions to poorer families specifically

Manila like leaves off trees.
