Molotow One4All markers are permanent acrylic-based markers. Suitable for both indoor and outdoor use, they are engineered and manufactured in Germany and feature a patented capillary system and a Flowmaster valve which offers a consistent paint flow to the tip of the marker. The acrylic ink used in these markers is dilutable with water or acetone and will dry quickly to an opaque, semi-gloss finish on nearly any porous or non-porous surface. UV-Resistant and lightfast, this highly pigmented, solvent-free hybrid paint covers nearly every indoor or outdoor surface. These markers can be used with any other Molotow spray paints and markers. Available with 2mm or 4mm tips.
