Either way, I asked for a 0.5mm signature pen in the college entrance examination, but I still used a 0.38mm full-needle refill, and the English subject was still blue. Hehe, I got 545 points in the college entrance examination. English 1 19, math 138, but Chinese, hehe 75. I suggest you use that habit, as long as the indicators are the same. Otherwise, if you are not used to using a pen, it will affect your performance.
