We recieved 9 orange balls directly from gophersport. We originally ordered the rainbow colored balls but received an email asking if we were an FRC team and asked us to correct our order. Out of our 9 orange balls, 8 weighed 0.62lbs(281g) and 1 weighed 0.60lbs(272g). The KOP boulder weighed 0.64lbs(290g). If you are ordering from gophersport the correct item number is
99-634 for the FRC version and they are ordered individually.
