The neck size is a standardized measurement used for bottles and closures, particularly in the packaging industry. It consists of two parts: (example 20/400)

1. 20: The first number refers to the diameter of the bottle's neck opening, measured in millimeters. In this case, it is 20 mm across the outer diameter of the neck.

2. 400: The second number refers to the thread finish or the type of threading on the bottle neck. A "400" thread finish indicates a single thread turn that starts and ends evenly, typically used for screw-on caps or droppers. This threading allows the closure (e.g., a dropper or cap) to securely attach to the bottle.
