Some Companies Use Deceptive Packaging To Have You Replace Products Sooner
Simply divide the bottle in half and use a spoon to remove the remaining contents if you are having trouble getting the very last drop of toothpaste or shampoo out of the tube. There are some companies that would purposefully engage in deceptive packaging practices in order to increase the frequency with which their products must be replaced.
For instance, several cosmetics brands design their mascara wands so that they cannot be used to reach the very bottom of the tube. Cutting a container in half guarantees that you will not throw away any money and that you will make use of every last drop of every product.
