This pressure spray bottle can be used for a variety of purposes. Use it to hold water to spray frog terrariums, raise humidity in vivariums by misting the enclosure or even to spray young dragons that find it difficult to find water at an early age. This bottle can also be used to hold dilutions of disinfectant to spray out cages for cleaning. These are just some of its uses! The large pressure spray bottle holds 1.5 litres of liquid.
