What I received is good quality product of varied length. The box contained exactly 10.0lbs verified on a calibrated digital scale. Product is well packaged in 2 layers of resealable bags The length of the strands do vary a bit and should really be listed as 3/4" or less as they are between 3/8" and 3/4". This will work for the driveway grass pavers I am making. I would prefer the strands had all been 3/4" for better strength. I knocked off 1 star for the varied lengths. Overall would buy again as the price was under four dollars a pound, and a pound goes a long way.
