HP 60 Tri-color Original Ink Cartridges

I wrote to HP and explained I scratched the plastic ink cartridge to see if it was made of GOLD, they are not HP just charges way too much for something that costs nothing to make. I worked in FOOD PRODUCTION and there are VERY STRICT FEDERAL LAWS ABOUT WEIGHTS AND MEASUREMENTS that must followed up and recorded. HP HAS NO SUCH MEASUREMENTS ONLY GUESSES AS TO HOW MANY COPIES YOU MIGHT GET. HP needs to be held to account for selling something they make for pennies for MANY DOLLARS PROFIT ON EACH UNIT.
