You are buying 5 x adjustable replacement aerosol nozzles, however as I have so many of them, I am including another 5 making 10 nozzles.  The nozzle is a 'male' type which fits into an aerosol with a hole to fit it into, not the ones with a small tube sticking out of the aerosol can. This type would need a 'female' nozzle.  The second row nozzles in the photo show what I mean.

Thank you for looking.  We have a lot of these so if you want much larger quantities please get in touch.
