Quick and to the point. 3 bundles of Zen pipe cleaners hard bristle, there are 44 in each bundle, giving you a 132 total. Each pipe cleaner measures approximately 6 inches long, making cleaning even easier. Zen the name you know and can trust for all your cleaning needs and 420 help. These are the ideal length for many preschool, kindergarten, elementary and jr. and high school teachers, as well as Sunday school classes for arts and crafts projects. Even those of you who repair old antique tube radios, T.V.'S and even the more complex ham radios/receivers (especially from 19181965) such as phyllo, RCA, admiral, zenith, hall crafters, sears, Brewster, Crossley, firestone, plus hundreds more. Here is a recent buyers testimony, stu and Trish, I purchased these pipe cleaners because I use them to clean the sockets of very old tube type radios. There is an entire community of old radio repair guys and collectors who are faced with not finding pipe cleaners at the neighborhood drug store. Not only that but most of these guys (I do not) smoke pipes.
