Catherine werdel a product designer designed this toothbrush with a clever slit down the center of the grip. The slot is long enough so that the end of a tube can be slipped in but narrows enough that it can push the viscous contents down to the open end.
With two hands and little skill required, you can easily press paste out, ensuring that those last few milliliters won&rsquot go to waste. The last dollops of paste left inside the tube might not amount to a whole lot of dollars&rsquo worth, but the point is recycling and not letting things unnecessarily go to waste.
