The Cthulhu Mod Iris Mesh BF RDA is the result of a collaboration within The Vape Nation Community. Featuring the option for single or dual coil mesh coils, direct to coil airflow, and multi-tier design elements. The Iris Mesh RDA makes using a mesh RDA extremely easy, by allowing for plenty of cotton to be stuffed in between the coils so there is never a dry moment. Included within this set is a pair of 810 drip tips to Two interchangeable Air Control Rings with differing air slots provide precise options so you can customize it to your likings. The 510 squonk-ready pin has holes throughout the pin to allow for even saturation when you squeeze your squonk bottle.
