ペンを横に傾けるとチョークのような筆、筆を真上に向けると半透明の筆です。チョークを使いたいけれど、しっかりした筆で作られるシャープさを失いたくないときにとても便利です This is a chalk like brush when you angle your pen to the side and semi transparent brush when your brush is angled straight up. Great when you want to use chalk but don't want to get rid of the sharpness created by having a solid brush
