Ready to revolutionize your vape pen? There’s nothing quite like this wickless metal and glass cartridge from the Kind Pen. While this might look like an ordinary cartridge, make no mistake: this wickless tank is an upgrade for your favorite oils. Made of all glass and metal, this cartridge won’t overheat or get clogged due to its caliber construction--you can also take much longer drags on a glass cartridge as opposed to plastic. Pure ingredients like glass and metal are always preferable to plastic, a cheaper alternative that could potentially leach toxins into your vapor. This cartridge also features larger 1.1mm intake holes, which are perfect for thicker oils. This tank is compatible with all 510 threaded batteries, just snap on your favorite, and you’re ready to go. This wickless cartridge is available in both 0.5 and 1 mL capacities, depending on how much oil you’d like to store.
