Ideal for delicately accentuating illustrations, the Ultra-fine brush tip allows for the production of fine and precise lines, making it a must-have for professional and amateur artists alike.

• How to use: Remove the cap and with the pen tip facing downwards, twist the opposing end of the pen clockwise 5-10 times to stimulate ink flow. As you twist, you will hear a clicking sound. If the ink does not come out, continue twisting the base gradually, checking the ink flow at the tip as you do so.
