ounce dropper bottle containing apx. 400 drops of unsweetened, concentrated flavor per bottle (white caps). A few drops can be added to any cigar, pipe tobacco, shisha, water pipe water, etc. It does not contain any nicotine; it is concentrated, unsweetened flavoring only. This product is available in dropper bottle, 1 oz spray bottle, or 8 oz. bottle. Although Tasty Puff Flavoring cannot be vaped on its own, it can be added to any e-liquid base, to enhance the flavor at about a 10% ratio (6 drops per tank). It does not vape well by itself and it is too strong to use on its own in this way, but it makes an amazing flavor enhancer for e-cigarettes.
