Get ready to own a piece of FC history! But that was just my first model, this kit includes a cera EO core with black mouthpiece, my latest threaded large copper body, a rock-solid-reliable slip cap large copper body, a mini-cera copper body, two large batteries, two small batteries, two extra switches, and a charger. All for only $160 shipped to your door! This body has a smooth-turning tailcap and an easy to push button: This body needs to have the cap pushed on and pulled off, but it will never break: This is my favorite body, the tiny body that uses AA-size batteries: The cap has to be pulled off to change the battery, but the easy on switch makes it effortless to use! I should also mention, the "large" copper body is much smaller than the ceramic Cera, and this mini-copper body is practically the size of a pen vape/ecig!
