This had proven to be the very best option if you want to make sure to always have your own sanitizer on hand.
A refillable sanitizer bottle for either spray or gel that sits in a key fob to clip on your bag or belt.
Its bad enough to have to constantly soak your hands in sanitizer but the variety and quality in different shops and premises can be extremely hard on your hands. This way you can choose your own product that is kind to you and stick with it.
It is also idea if you have kids that you want to send out in the world knowing they always have protection if needed.
