Wash the pen immediately after use, do not put on the pen sleeve after washing, soak up the remaining water and straighten it out. Put the pan upside down in a cool place or store it with a pen curtain. Do not expose the pen to the sun.
Don’t lick the hair in your mouth; don’t use it outside writing or painting; can’t use it in solvents; the nib cover is used to protect the nib during transportation. Once the pen is used, don’t put it on again to prevent the bristles from decay and hair loss.
