The Kinetronics ASC-BP is an anti-static, microfiber cloth that has been specifically engineered for cleaning photographic films. The 10" x 18" (250mm x 450mm) orange cloth has stripes of effective conductive fibers knit every 1/8" or 4mm that dissipate or drain off static charges.The Kinetronics ASC-BP is not wet or "soggy" and exposure to air won"t dry it out. The ultra soft cloth is so gentle you"ll feel comfortable using it on sensitive negatives and transparencies. Hundreds of thousands of small pockets in the microfiber cloth aggressively capture the dust and dirt from the film. The Tiger Cloth comes packaged in a zip lock bag.
