These Sennelier Brush Pens have real synthetic fibre brush tips and thanks to the real fibres, the application of the colour is more fluid, constant and linear, taking advantage of the internal capillarity of the brush to facilitate the dispersion of the colour. In the same gesture, the artist can create extremely fine and very wide lines (up to 10mm) with a continuous flow of pigment based ink, by simply varying the pressure of the tip applied onto the paper. The pigment based formula is enviromentally friendly and exclusive to Sennelier.    These Sennelier Ink Brushes are equally suitable for Lettering enthusiasts, Bullet Journal fans and watercolorists.    The colours are blendable, water soluble and permanent when dry   Contents Iridescent Lemon Yellow Iridescent Orange Rose Iridescent Ultramarine Blue Iridescent Dark Green Iridescent Black Iridescent Silver
