At just 4 inches tall with a feather-light build, the RUBI is pocket-friendly yet powerful. OCELL Ceramic Coil Technology extracts full-flavored clouds from your favorite eliquids and oils while maintaining smoothness and potency. A temperature regulated battery maintains the ideal temperature for liquid and oil vaporization, while an air-activated heating system does away with the usual power button for a more seamless user experience. Just inhale and the RUBI vape does the rest, and instantly. While many eliquid vapes feature pre-filled closed system cartridges, the KandyPens RUBI ecigarette boasts an open system that can be refilled with up to 1ML of eliquid or oil. Developed and designed in the USA and made by hand, the RUBI vaporizer delivers the best liquid vaping experience yet with innovative patent-pending technology and a lifetime warranty on the battery.
