Hi, I'm just looking for some 0.2mm mechanical pencil, but surprisingly I can't find any in my city (in México) just via amazon or similar, but I find a lot of 0.3mm, that could be enough? it can give me good detail to not requiere a 0.2 mm? actually I use a 0.5 and a bit of sand paper to sharpen enough for small details, I didn't know about the 0.3 and 0.2 mm.
