Clearly for Art Modeling Sheets are a unique material can be molded into dimensional embellishments when heated. Different than Shrink Plastics in that it does not shrink and can be reheated and reshaped as desired. Becomes solid once cooled without cracking or breaking. Contains three 8" x 10" sheets of modeling film clear transparent. TWO NEW materials are opaque, but have the same magical properties of the original CLEARLY FOR ART sheets. They can be heated, shaped & reshaped until you are completely satisfied... they can be stamped or die cut...they can be embossed...and when they cool, the product is very sturdy.
