When applying deodorant, you can never be sure that you have used enough.
Today’s invention provides a way to make more effective use of deodorant in the form of a solid stick. The stick material would resemble a glue stick or lipstick, being supplied in a tube with a screw mechanism to advance the deodorant.
The stick itself would be clear and non-marking but it would have embedded within it a layer of different perfume every few mm along its length (or whatever spacing was required to provide an armpit with adequate protection).
The stick would be applied to armpit 1 until a new perfume was sensed by the user and then the process repeated on the other side until another new perfume was smelt. Each armpit would smell different, but that might be used to provide a quirky advertising advantage.
