Shrink-Me Plastic is a thin, clear and flexible polystyrene plastic that allows you to create your own charms, embellishments and jewellery. Prior to heating, it can be coloured with permanent markers or colour pencils, and cut into shapes. Oily or waxy substances are not suitable because they melt or burn in high heat. Heat with a conventional oven on 160 degrees Celsius for 3 minutes or until flat, you can also use a heat gun on low heat. The design will shrink, become thicker and more rigid while maintaining the coloured design. Please note that the design will not always remain proportionate. The pigment will intensify while the plastic is shrinking.
