i’ve seen more clipper guards with mm than with those single digit numbers, which is good because those numbers told me nothing, if i recall correctly they do not match the hair lenght they’d cut to but instead are just numbered from smallest to biggest in the set
What? Clipper guards are single-digit numbers like 0 or 2
I agree, but to be fair to OP, 5 and 9 are also single digit numbers.
with no other characters
My Andis set has a number, as well as both metric and freedom units on each guard.
