My pen Alpha I bought the thinnest here because the attached pen felt thick. You can draw a very thin line, but you can not bake it unless you move it much slower than a thick pen. Because it is higher than other places, I bought it as a next step, but I will also consider using it for a while and buying a pen.
Until now, I used a 1 mm pen tip, but because I absolutely need a fine line. The feeling of use is very good that I can express details as well. Because it was necessary early, it was saved for immediate delivery.
