Flavor: The dynamic duo of blueberry and watermelon flavor do some heavy lifting in the outstanding Blueberry Watermelon Raz TN9000. The watermelon is a mixture of the popular confection and fruit flavors that make it a great standalone vape. The blueberry bursts with the tart and sweet notes that make it shine. Together, the whole flavor package is greater than the formidable sum of the parts.
