Sorry, bale is probably not the right term. I just call it that cause it looks like a small hay bale. It says Premium quality horse bedding on the side and comes in a bale shaped bag that measures about 30" X 18" X 11" (I just took a tape measure to it) and says 'All Natural aspen fibers', 'Multi screened to minumize dust', 'highly absorbent', and the weight is listed as 'more then 43 lbs' I suppose the weight is variable depending on how much moisture is contained in the wood fibers. In any case, it's a heck of a lot cheaper buying it from a farm supply store then from a pet shop or from the pet section of a department store.
