After a level of moisturizer drops below that point where the inside tube/straw ain't going to cut it and with each pump, you the user gets diminishing returns. For a while, you can keep moving the tube around to get some (but not all of the moisturizer).
So? How do you get all of the moisturizer (or other body cream) from the bottom of a plastic pump bottle? Or do you just give up and throw the plastic container away - with the remaining ounces of hand or body cream? Because heck? No place will ever allow this plastic bottle to be properly recycled with any remaining substances in it.
For visual context:
I guess at one point, I could just cut the plastic bottle open and manually remove the hand cream in that fashion. With the likes of shampoo bottles, one can add water to the bottle (shake it up a bit) to get most - if not all of the remaining shampoo. That wouldn't be a good thing for moisturizer.
