This box of 500 nails are ideal for the DIY'er.  You go to the big box store and they have them in 2500 or 5000.........okay for the contractor but way too many for around the house.  This way I have a good assortment of the nails that can be used in my gun - without breaking my wallet.  Sometimes when you can't find the nail you need at Amazon, check out the Home Depot that has tool rental - you can get them there in small amounts....they don't gouge you either!  These nails are quality nails and I recommend them without reservation, my gun has never jammed or had a malfunction.
