Sometimes you need a little spritz and sometimes you want a powerful mist!
Fill your bottle with liquid—I fill mine with water. When you hold down the trigger on the Continuous Spray Bottle, the liquid inside is released in a fine mist for as long as you hold the trigger. It's a great solution for spraying a large amount of mist over a large area.
The bottle is lined with a flexible bladder. I suspect that that is what helps to keep the contents under pressure without having to prime the pump every time you use it. But that's a guess on my part :-).
The continuous spray bottle can hold 10 oz of your favorite product.
