Worbla is a thermoplastic modelling material! Use hot air, water or steam (min.90 degrees C) to shape the plastic however you want. The material is heat-formable and solvent-free. It hardens very fast, is sandable and because of the extra glue on the shiny side, it is very easy to attach several layers.
Please note, this material is more rigid and not as detailed as the black worbla. Also, sizes will not be exact due to the difficulty in cutting.
