The Damn Vape Foxtail-M Vape Cotton is designed specially for mesh rebuildable atomizers such as RTAs or RDAs. Since it is agleted, there is a plastic sleeve on the end, so it makes it incredibly easy to slide this cotton through the mesh strip or coil. This is 100% organic cotton as well, so there's zero taste and little to no break in time. Another great feature to the Foxtail-M Cotton by Damn Vape is that its cut to the proper length for mesh style atomizers, and would be perfect for the Damn Vape Doom RTA.
