There is no combination of fruits more iconic than that of blueberry and raspberry. The sweet, sour and sugary flavors go together perfectly. That is why Fume’s Ultra Blue Razz disposable vape is a must buy. The sweet flavor of blueberries balances perfectly with the sour tang of raspberries. With a large battery allowing 2500 hits to boot, this is one device you’re going to want to get your hands on.
