Green Apple Crispy Treats Ejuice by Ethos Vapors tastes absolutely fantastic. The classic Rice Crispy Treat flavors of marshmallow and Rice Crispy cereal go extremely well with the taste of fresh, crisp green apple. The inhale delivers a sweet and creamy marshmallow flavor that creates an excellent base layer to build upon. Next comes in the crisp, sweet and slightly tart green apple flavor that blends together with the rice crispy treats cereal. The flavors continue to develop throughout the exhale, leaving behind a sweet, creamy, savory and fruity linger.
