Acrylic marker ink is similar to acrylic pigment pigment, particle diameter and other solvent granularity is not consistent, after a long time there will be stratification phenomenon, so before opening the cap to use need to shake, will be shaking the ink, and open the cap to be careful; in order to make the pen out of the ink is smooth, the general pen and the pen shell of the gap will be bigger than the ordinary watercolour pens, if open the cap is too forceful, or flinging the pen, then, there will be a leakage of ink! If you open the cap too hard or shake the pen, there will be ink leakage.
Before the first use, the nib is no ink, you need to press the nib until the ink is completely soaked in the nib, then you can start to use it, during the use of the nib do not let the nib exposed to the air for too long, it is best to cover the cap in time, otherwise the nib is easy to cause blockage of ink after drying.
