The alcohol dries right away, and you don’t need much. Also, surprisingly, it’s not hard on the hands at all. I have very sensitive skin, but did not have any skin irritations from using this hand sanitizer on a daily basis. I got the four 32 fl oz bottles. The price is not bad for the amount, and it will last a while. I also bought the blue small glass bottles with pump - very nice quality. I definitely recommend buying!
