ONE4ALL refills are permanent, UV-resistant, and non-toxic acrylic paint that can be diluted with water or acetone (to 1-3%) and will dry quickly to an opaque, semi-gloss finish on nearly any porous or non-porous surface. This paint is designed for refilling Molotow One4All Acrylic Markers, but can also be used like regular fluid acrylics and applied with a brush, sponge or knife. It can be mixed with other Molotow Refill colours or poured straight into the open marker. The paint pours cleanly from a side tap at the top of the bottle. The 180ml refils are available in Signal Black and Signal White only.
