Speedball Flex Fabric Screen Printing Inks are an advanced water-based ink designed to be flexible across a variety of materials. The inks deliver bold, rich color whether printing on light or dark fabrics. Ideal for use on cotton, polyester, rayon and synthetic fibers while resisting cracking or peeling when fabric is stretched or pulled. The fabric will stay soft to the touch, and the ink is permanent when properly heat set.Details:Ebony8 fl. oz.
