Our Flit brass sprayers fit most soft drink bottles (up to 2 litres) and trigger spray bottles. They pump/spray on both the forward and back actions. They are adjustable to give a beautiful fine mist as well as a far-reaching stream. The double sprayer has swivelling nozzles making spraying the underside of foliage a breeze. The single sprayer has a fixed nozzle. Great for arthritic hands.
