A range of exquisitely rich opaque inks with high pigment content. This makes them unsuitable for use with a fountain pen; they're best used with dip pens and brushes. Gold and silver inks contain metallic particles, so the bottles will need to be shaken periodically while using. Particularly effective on dark-coloured paper. 30ml bottle. Pigment ink contains pigments of organic origin. Their molecules are larger than those of traditional inks, which makes them more resistant to light and humidity. The pigments settle, dry and stick to the paper without penetrating it, which gives your drawings a very particular style that is reinforced by the use of dark paper. Use the ink with a writing instrument containing a large nib to facilitate the passage of the pigments. Compatible with Jacques Herbin reservoir markers, calame, brush, quill pen and nib holder. Bottle delivered in a resealable cardboard case for easy storage.
