Swab 17022 has a four-inch long natural polypropylene rigid handle with a round white mitt head composed of 100 PPI zapped polyurethane foam. The mitt has a diameter of 1-1/4 in., and the soft zapped foam allows for maximum absorbency and fluid retention. Swab 17023 has a six-inch long natural polypropylene handle with a stiffer 100 PPI white polyurethane head, 1-1/4 in. in diameter. The flexible handle and larger internal support, combined with a slightly rougher texture, allow more vigorous cleaning and polishing.
