## Description

This multi-colored acro ball can be used smartly for notebooks, documents, and color-coding. ■ Writes smoothly The acro ink used for acro balls is 1/5 the viscosity of a regular permanent ballpoint pen, resulting in a smooth ink that is close to water based and allows the ball to spin smoothly. ■ Write in darkness Acro ink has a low viscosity which allows for more ink supply to the nib. Ink penetrates deep into the paper fibers, resulting in uneven and dark strokes. ■ Firm grip Acroball grip is made of soft, non-slip rubber. In addition, the surface has a tire pattern that is non-slip and uneven

1本目のインクが切れたので再度購入！ なんといっても書き始めからスルスルと転がる書き味が魅力！インクが軽やかに流れ、なめらかな筆記感を楽しめます。 洗濯バサミのようなクリップが意外にも邪魔にならず、ボディにも適度な重みがあります。グリップは握りやすくかなり手にフィットするので、長時間使用でも疲れにくい、そんな4色ボールペンです！
