It's compressed air in a can. Pricey for what you get but it does the job.

Great Product, and Great Value!!!!

Good value but these dusters are getting to be too expensive at nearly or slightly over $15.00

Its compressed air.....it does the job

Really nice 'liquid air' that work well and seem to last

It’s can air and works great on so many things, including the cats for behavioral issues!

Works great for removing dust from my computer and especially from my sewing machine.

I bought these to clean some decorative flowers, and of course keyboards.

Great for dust that gets in creases and crevices

Falcon dust off is great I use it all the time
