The bottle is much smaller than I expected for some reason-- it's definitely purse-sized. It has an insert arm which folds out (a bit like WD40) and goes in your ear. You puff it 2 times in each ear....each day until your ears are cleaned out. I don't know exactly what is in it, but it works just great. My ears weren't super-plugged but enough to notice a difference. It's nice to have the option to do things like this at home yourself, during the pandemic.
