If build your own coils and use your wicking material of choice, then an RDA or RTA is a great deal from our store for you. These tanks are made to offer great vapour production and rich flavour. Some of them are better for experienced DIY vapers but some are for beginners who have not made their own coils before. At Vapesale24.com you can find cotton wicking material and DIY coil wire to your personalised e-cigarette setup.
