  How to define the closed size of Cosmetic Treatment Pump?
  The thread closure size is represented by two numbers, separated by a hyphen or slash.

  The first number refers to the inner diameter of the bottle cap (mm) and the outer diameter of the fish tail of the bottleneck.

  The second number represents the "GPI" or "SPI" thread finish, which refers to the ratio of the height of the bottle cap to the number of threads on the neck of the container. The most common numbers are -400 (a full turn of thread) and 410 (a half turn). Some bottles have a -415 bottleneck, which is two complete circles.
