Shed-resistant white fabric for a virtually lint-free finish with all paints, enamels, varnishes (satin, semigloss, and gloss). Dense fibers reduce dripping and splatter. Polypropylene core resists water, solvents, and cracking. Open 3/4 In. core makes cleaning easy and refills cost less. Use with any of the Jumbo-Koter cage frames.
