Vapor Talk Dulcis – Our most popular flavor! A Tobacco liquid with hints of caramel that is sweet (although not too sweet!) and decadent. Some of have stated it reminds them of toffee candy, some cookies while others have suggested a mix between butter and syrup. We’ll let your taste buds be the judge. And for those of you wondering how it’s pronounced – dull (like a dull day) sis (like sister) Enjoy!
