Finetec
These pearlescent colors are handcrafted in Germany and dissolve with
water and a brush, just like traditional watercolors. Lightfast and
pigment-rich, the paint can adhere to a variety of surfaces including
paper, wood, cardboard, clay and stone. They work well with brushes and
dip pens; simply brush the color onto a nib to use it as calligraphy
ink.
