Worbla has been taking the costume and crafting world by storm. Heat with a heat gun or hair drier. Worbla can be used to make all kinds of armor, weapons and props. Worbla plastics are different from other thermoplastics. They’re thinner than Wonderflex and handle curves better than Sintra, and Worbla products are non-toxic and don’t need special tools. You use hot air, water or steam to shape the plastic however you want. There’s no waste because your scraps can be conditioned and 100% re-blended. These leftovers can be molded to act just like putty.
