The empty pens are available in different sizes and different tips. This allows to create easily individual sketches, drawings or signa- tures on diverse surfaces such as paper, canvas, wood, primed metal or primed plastic.
On the label is a blank field for you to mark the colour you have filled the liner with. One colour per liner is recommended. Colour mixes should be made before filling into the liner.
For filling, remove the cap and the valve. Fill the liner with Schmincke Aero Color up to a maximum 2/3, by using an eyedropper. Put the valve back in place, screw the cap on tightly and shake the pen. By depressing the tip repeatedly, the acrylic ink is pumped into the nib and the pen is ready to use.
