It is a pen with a similar shape to the marker I made for myself.
It is a brush that is very easy to use personally because it is strong and thick and weak and slender, and since it is for graffiti line art, it may not be suitable for gutsy coloring.
自分用に作成したマーカーと似た形状のペンです。
強でガッツリ太く、弱でほっそりとするので個人的にとても使いやすいブラシです、落書き線画向けなのでガッツリ色塗りは向いてないかも知れません。
I'm messing with opacity, so please use it with a satisfactory transparency. 
If it's about shadow painting, you can paint it just right.不透明度いじってるので満足できる透明度でお使い下さい。影塗り程度なら丁度いいくらいに塗れます。
