40 bucks, you're ready to go with nothing more than a torch, a can of butane and your favorite BHO/Hash.
It's 10 dollars more than just the tube and banger, but they throw you a flower ball, a carb cap, dab tool and you're ready to dab out the box. If you add these things from the site individually you'll pay over 20 dollars for them.
Now the flower bowl I could pass on. A second carb cap or something else dab related might be better for some. But for those who like to use one tube for both flower and oil you're ready to rock..
Hope this helps I like the rig functions right basic but that's all you need.
