This is a blood vessel painting pen that I made for myself because I wanted to save time. 時短したくて自分用に作った血管塗りペンです。
It is a pen that draws the blood vessels that stand out of the body.
Please use it when you want to draw a blood vessel as a finish after you have finished writing.体の浮き出る血管を描くペンです。
大体書き終わった後に仕上げとして血管を描きたいときにお使いください。
