“Last drop” is a new kind of ink bottle ensuring you use up the last drop of the ink. For the ordinary ink bottle, there is always some ink left and the completely suction for ink with a pen is difficult. “Last drop” ink bottle is designed with a sunken part at the inner bottom of it, so the left ink could flow together. You are allowed to use up the last drop of ink easily and the waste is avoided.
