Double Helix 510 Drip Tip

Double Helix 510 Drip Tip, With a large outside diameter at the bottom for strength and a bore that is larger at the bottom than the top, to function as an expansion chamber.
Has an internal double helix for strength as well as to reduce pop spatter and force vapor to travel further before it gets to your mouth.

Now that I have used this for a full day, I can say that it makes the vapor very dense and flavorful.
