Who said you need to sacrifice options for portability? With this dual-use vape that fits in your pocket, you no longer need to. With the ability to vape both oil and e-liquids all in one pen, this Slim Oil Vape Pen from Kind Pen will easily become your go-to so you can have it all while maintaining a busy schedule. A wick chamber can be filled with either oil or e-liquids depending on your preference--we don’t recommend putting concentrates in this pen as they will get stuck in the wick chamber. This pocket vape might be small, but it’s smart: you won’t find any buttons on this vape as it’s air activated when you inhale. This auto-inhale technology saves you on battery time and needing to click a button 5 times. In addition to the slim oil vape pen, this kit comes with a USB charger. Choose your favorite color Slim Vape Pen, available in red, green, blue, white, black and gray.
