Button classification:

First, the difference in button size.

That is to say, we often say 14#, 16#, 18#, 20#, 60# and so on. The labeling formula is: diameter = model *0.635(mm). If we have a button in our hand, but we don't know its size, we can measure its diameter (mm) with a caliper and then divide it by 0.635 to get the result we need.

Second, distinguish by perforation.

1, blind button: usually on the back of the button, through the radial perforation of the button.

Eye-opening button: Directly through the front and back of the button, there are usually four-eye buttons and two-eye buttons.
