1. What is your analysis of the basis weight business?The problem begin when Wet-Land Drilling, Inc. had filed a complaint that the bags it received from Bayfield were short-weight, according to antecedent send the weight of the bags used to be 50 power hammers, in time the tonic arrivals show a weight of 47.5 pounds per bag, causing a conflict to the gild.
