Roll on is a packaging good not only for antiperspirant!
Roll on will work great also as a packaging for disinfectant liquids.
We got a chance to test that on ourselves, as from beginning of CoViD-19 outbreak all our employees are using it.
The great advantage is that it’s incredibly easy to use- you just need to unscrew the cap and apply the liquid onto your hands by rolling the ball. Moreover, thanks to the small size, we can always have it at hand in our pockets.
