Add-it droppers are simply put a high quality liquid that enables you the angler to customise your own tastes and smells for Add-it pop ups, or any other pop ups you may need to recharge. Just a few drops dripped over the pop ups and a quick shake will create a super unique hook bait for you, just follow instructions on the label. Choose from the several flavours and combinations available, if you want to create an even higher unique smelling/tasting pop up try using two dropper flavours and mix together.
