If you have a vaporizer as epic as the Volcano, it is obvious that you need a grinder that lives up to that standard. The Volcano herb mill XL does just that. With a diameter of 9 centimeters, you will have more than enough space for your herb. The ribbed edge gives you a better grip and makes it look even more badass. Besides, did you notice that the bright orange colour matches with the colour of the Volcano balloons? What's not to like?
