Awesome product. I purchased this to make a carboy cleaning brush for home brewing.  My initial concern about the 'toughness' of the material to withstand attachment to a drill are completely alleviated.  The material is also super absorbent, non-abrasive and has a nice tacky feel when wet.  Be aware that it dries hard pretty much like a natural chamois when dry.  This size is big enough to make 4 carboy cleaners.
