Liquitex Flexible Modeling Paste 8oz by Fanmats
100% polymer emulsion that dries more slowly than other modeling pastes to a hard yet flexible surface. Used to build three-dimensional forms and heavy textures on supports that may be subject to flexing or movement. Adheres to any non-oily absorbent surface. When mixed with acrylic colors will act as a weak tinting white while increasing thickness and rigidity.
