Vaping wires, wicks, cotton and vape mesh are all items that are designed for rebuildable atomisers including RTA’s (rebuildable tank atomisers) and RDA’s (rebuildable drip atomisers). Building your own coil wire for vape devices requires experience and good knowledge of battery safety and Ohms law.
There are different types of wick you can use from stainless steel vaping mesh, silica wick to organic cotton. Pure cotton Japanese wicking pads are one of the best wicking materials you can get. It wicks better, boasting fast absorption and makes dry hits easier to avoid. It is more consistent than other wicking materials.
