Finetec Watercolours (Coliro Pearlcolors)

Finetec, now made as Coliro Pearlcolors, are pearlescent watercolours made from mica pigments bound with gum arabic. Add water and they can be used straight from a dip pen, which is why calligraphers reach for them where a metallic ink would be too thin.

The range covers individual refill pans in over eighty colours, ready-made palettes from the gold and silver sets to themed collections like Art Deco and Autumn, and empty metal boxes for building your own.
