These are sponges for cleaning beer lines in a beer server. I think there are about 100 pieces per sponge. This is a set of 3. The set is discounted. If you want more, please comment. The more sets you buy, the cheaper it gets. Using these when cleaning the lines of a draft beer barrel will remove dirt from the inside of the hose, making it less likely that the quality of the beer will deteriorate. Available for immediate purchase.
