The Electro Barrel is a powerful device packed into a friendly, easy-to-use design. The toxic barrel is an OG Ooze design, but this e-rig is hiding something special under the hood. The C-Core Onyx Atomizer powers the Electro Barrel. This provides insanely potent, smooth airflow, maximum flavor production, and more even heating throughout your session. It also ensures the vapor you inhale is 100% heavy metal free.
