The Wismec Theorem is designed by Jaybo of TOBH fame. The Theorem features multiple atomizer sleeves and two airflow control rings, a brand-new Notch Coil, and an very easy to fill top fill system. The Theorem is the first to utilize an open wicking system [no, I don't know what this is supposed to mean either], a combined top airflow juice plug and a relatively leakproof "cup" design, which makes it very easy to build and refill. Theorem RTA brings a different vaping experience.

• Width: 22mm
• Height: 46mm
• 3.5 post deck - 2x negative posts and double wide positive post with dual screws
• Can be set up for single or dual vertical coils
• EZ-Fill port behind the deck
• Small gap around the deck - no vaccuum lock!
• Fully adjustable rear and top airflow
• 2.7ml capacity
• Includes 2x glass and 1x sleeved glass
• Will not leak while upright, but will probably leak while on its side or upside down

Note - The notch coils that are included are unfortunately not ideal for this atomiser. They are huge and make the glass get VERY hot. We've seen melted orings and cracked glass from this.
