Hi! I Have to ask you guys, what os The difference between regular and bugpin needles ? I mean if I use 07SEM0.30 needles the 07SEM gonna be just thinner ? Or it is something like 0.20? Couse I’m really confused . I know that they have long taper always and they are thin but it is same like 0.20 needles or they are thinner ? Couse usually I don’t see something like “07SEM0.25 bugpin “ is just “07SEMbugpin “ so idk 😐 can somebody explain to me what does it mean exactly?

Thanks !
