Packing of "shake" ointment

Generally, after using the ointment for a period of time, the remaining ointment will be concentrated in the middle and lower part of the tube. So it often needs to shake the tube to move the ointment to the front. This design extends an obvious semi-circular sign at the end of the tube. The flat, thumb-like shape is the most suitable place to pinch when shaking the tube. The design of this sign makes ointment shaking more smoothly.
