The Buddies Convertible Battery is unique in that you can use it in multiple ways. At the top of the battery, there are two connections. The very top part with the glass mouthpiece is held on by magnets. When opened, the consumer can place a dab in the cup with the quartz heating coil. The other way to use it is to unscrew the second top piece and substitute it with a universal 510 Cartridge and use it as a normal cartridge pen. This battery is button activated and has three variable temperature settings for the consumers comfort. First in its class, the Convertible is paving the way for high quality vaping in multiple ways with one pen. The Convertible comes retail ready in individual packaging and sold in a master display box, ready to show!
