The Ooze Electro Barrel is our very first e-rig powered by our C-Core Onyx Atomizer. This ensures every dab is heated evenly, making terpene flavors taste stronger and increasing the size of your clouds. It features a removable water chamber that makes each hit even smoother and air flow is controlled by your finger through a hole in the lid. Always enjoy 100% heavy metal free vaping with this device!
