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.

Buy 100 of the spark plug gaskets and you will not find a better price on new gaskets.

They are round, which is good, and they fit my spark plugs, which is also good.
