Perfect to put your hand sanitizer into. Put in cup holder in car and stop with the flip top bottles. Order a gallon of the hand sanitizer and fill and keep reusing. The bottle is round at the bottom interior, allowing use of mostly every last drop of fluid. Dede had to find something to avoid turning a bottle over in the car and squeezing out a ton of hand sanitizer! User for facial soap and more too. Reuse the bottle. All Sales Final.
