They were reasonably priced, shipped and received promptly, were the right size. I didn’t count them, but no reason to think there were less than 100. Which should last me quite a long time - using them on a classic car with 2 plugs for each of it’s 6 enormous cylinders.

Heres the deal folks...All aircraft engine manufacturers specify using a NEW gaskets when removing and replacing aviation spark plugs. If you run a Repair Station or you are an A.I. you best be using NEW gaskets (and billed on your work orders) to avoid potential liability issues.
These generic branded M-674 gaskets are the correct Rockwell hardness and dimensions. We use thousands of gaskets per year and these Aircraft Spruce gaskets are now our #1 choice.

I just watched a video on youtube of a fellow taking old gaskets and heating them with a blow torch to anneal them, so he could reuse them....even though they were crushed and had a raised lip. I like the idea of reusing things, but when a brand new copper gasket costs about 36 cents, that seems pretty stupid. Buy a handful of gaskets and let them sit in your tool box, and use them anytime you take a plug out...
Good product, very low price.
