Incorrect spelling of “squishy,” the adjective refers to a quality much appreciated in prostheses (especially in packers), namely softness. Very stiff packers make the crease of clothes unnatural or seem exaggerated during everyday life. The sensation given by the prosthesis must be soft and natural, but not sticky. The material must also be easily washable, without the use of excessively specific or expensive detergents. A material with these characteristics is a high-quality material, which contributes to making the prosthesis as a whole a valuable and desirable object.
