Just like your standard RY4 blend, but at double the potency, try RY4 Double for the straight up taste of slightly sweetened delicious tobacco. In a DIY e-liquid mix, we recommend trying RY4 Double with Honeysuckle, Vanilla or Menthol. Try it mixed with Smooth. Double=DOUBLE STRENGTH flavor. Start at 0.5%, and then adjust to taste

This is a very popular tobacco blend with caramel tones.
