Smoktechs just tube and end caps? Where?

[<---cop]

I'm looking to buy 5 or 6 tanks to make rotating flavours easier.
I remember some vendors were selling tubes and endcaps for smoktech tanks for less than $5 without the carto or drip tips.
The Electronic Cigarette Super Store | myvaporstore.com have them but they don't ship internationally

Does anyone know who else stocks them?

Carto Tank Mods ....not smoktechs...or whether they ship INT BUT..............

Thanks for the reply. Good option.

I would prefer to buy some end "caps" rather than grommets if I can.
Just looks more finished IMHO.
