Theorem Atomizer, Designed by JayBo, Inspired by SMM, is Wismec’s first Drip Tank Hybrid featuring the new and exciting Stainless Steel NotchCoil. This Atomizer is the first to utilize an Open Wicking System, a combined Top Airflow Juice Plug and a Solid Leakproof Sleeve Design. Removing the glass sleeve from the deck exposes the build area making it completely accessible and easy to install both cotton and coils. Removing the Top Airflow Cap simultaneously exposes the fill port, allowing the user to easily refill the Atomizer without alerting their airflow settings.
