This is a high quality, long lasting, spray bottle with a heavy duty, high quality, adjustable spray head. You can adjust the spray from a water pistol type spray (good for killing bugs from a distance) to a super fine mist. Just turn the nob to adjust. It comes with an improved waterproof label with dilution instructions.
The label has large checkboxes so you can mark the dilution of each bottle. That way you can have different dilutions premixed and available immediately if you purchase more than one spray bottle.
