This tank is made of "flavor safe" Polypropylene.
It has a 1" OD and holds a whopping 5 ml's including the standard 35mm length cartomizer.
It's a sturdy, hefty little bugger... Texas sized!
Tank includes 2 Food Grade Silicone grommets and O-rings, a 35mm Cartomizer and Drip tip and comes drilled with my normal side fill hole. (Drip tip color may vary, you can request your 2nd choice in the order comments section. Ming style tips NOT included.)
(Note: This is a tight fitting seal, the O-ring can be left off and still retain a leakproof seal. I add it for reinforcement to handle a little rough treatment without leaking.)
