Worbla's Black Art is a black, low temperature, sheet thermoplastic, with a finer texture than classic Worbla. Heat it up with a heat gun, shape it as needed, then once it is cool you can paint and decorate as you wish. It can be used for crafts, costumes, props, and much, much more!
PROS: Needs less priming than Worbla's FInest Art. Handles curves really well just like regular Worbla. Good for doing fine details.
CONS: Less sticky than regular Worbla, so needs to be heated longer/to a higher temperature in order to get it to adhere to itself, foam, or other thermoplastics. Best if you already have experience using regular Worbla.
