The Indestructible RDA by JayBo Designs is the evolution from the critically acclaimed TOBH Atty, with an emphasis on improving overall design, durability, and functionality. Airflow has been designed at a specific height in an effort to maximise the overall effectiveness with nearly every type of coil configuration, with dual 3mm holes on each side, for a consistent and smooth vaping experience. A single air hole option is also integrated for single coil builds.
