Hellvape Shoelace Organic Cotton – is a 100% natural, organic, unbleached, pesticide free wicking material suitable for all RDA & RTA applications. Hellvape organic cotton has a superior absorption rate for rich dense and flavourful vapour, makes wicking easy and requires no ‘break-in’ time since it is tasteless and odourless, and if used correctly can last up to two times longer compared to other brands.
