Realbrush PRO are modern paint brushes enclosed in a marker housing (so-called Realbrush markers) that offer a large selection of pre-made colors. They allow you to create an infinite number of additional colors and their shades using popular techniques of mixing and applying colors. They are made using “free ink” technology, so the color intensity remains unchanged until the last drop. They contain 2.4 ml of non-toxic, intensive dye-based paint or, for neon colors, pigment-based paint. Brush size: 4mm.
