The Kanger Subtank Clearomizer Glass Tube is a pyrex glass tube made specifically for subtank mini.
Kangertech Pyrex replacement glass tubes for the Kangertech Subtank Mini.
These are the transparent glass so it is easier to see how much juice you have left in your tank even in lower lighting situations. Great gift for the vaper who is rough on tanks and an even better idea to just always have a back up. If someones glass breaks and they don't have a back up, they are more tempted to go back to analogs ( real tobacco cigarettes ) than the person who can just slip a new glass in. Great price for a Greater item! All offers are given serious consideration.
