Product Features:

  • Can write smoothly

    The acro ink used for acro balls has a viscosity that is 1/5 that of general oil-based ballpoint pens, making it a smooth ink that is close to water-based, and the balls rotate smoothly.
  • Can write deeply

    Acro ink has a low viscosity, so the ink supply to the pen tip is ample. Since the ink penetrates deep into the paper fibers, the handwriting becomes even and dark. 
  • Can hold firmly

    The grip of the acroball is made of rubber, which is a soft and non-slip material. In addition, the surface has a tire pattern consisting of non-slip irregularities.
