Oh ok i seen that before it looks just like my acorn
tank from parkesvaping.com a very inexpensive but works
tank you can see that one if you click my screen name and go thru my photo albums i have like 4 of them in xl and regular size.
Matter of fact i borrowed one of the grommets to use as a bottom for the vision stone tank so i can easily change out there low res atty to something with higher ohms.
