Dede prefers to pump her hand sanitizer in her hand in the car. So, she got some of these for you too! Buy a gallon of hand sanitizer, fill this bottle with it, and leave in your car cup holder. Awesome efficiency! Dede uses the small one in her car for hand sanitizer, the small one for dish detergent at work, and can be used for all types of things. The round inside design should allow you to use every drop of fluid. Be sure to take the pump out of the bottle before first use, twist it by holding the stem to pop up the pump, then fill the bottle and insert the unlocked pump lid. All Sales Final.
