Super Sculpey Flex Firm 454 g is a flexible oven-bake polymer clay with a firm, precise working consistency. After baking, it remains rubber-like and bendable, making it useful for fine detail and stable parts that must remain flexible.

The clay does not air-dry, allowing time to refine forms, textures and joins. Cured pieces stand up well to handling and can be sanded, cut, drilled and painted.

Bake at 130 °C for 15 minutes per 6 mm of thickness. Use an oven thermometer and let the piece cool completely before assessing its flexibility.
