Could you eat this whole pack of Sour Lemon in one sitting? He's sour! But he's sweet? It's so confusing, but I keep eating it! Each package of Flossie contains 40 calories and is crafted with attention to detail. It is gluten-free, vegan, and artisanal. To maintain peak freshness, it should be stored in a cool, dry place away from direct sunlight when not being showcased. Flossie has a shelf life of over six months. For the best experience, it is advised to enjoy Flossie right after opening, as it is intended to be a perfect single serving of cotton candy.
