Introducing the latest DL design from Pulsar! This 510-cartridge vaporizer doubles as a writing pen, complete with functional ink. Designed to fool any onlooker, hide it in plain sight within a shirt pocket or on a clipboard. To get started, simply remove the cap and screw in your 510-threaded cartridge of your choice. Activate the vaporizer and cycle through the five voltage level options with a single click for your ideal session. This device has an eight-second preheat function, preventing cooled oil from clogging the airflow. The discreet LED indicator light lets you know the current voltage level and when preheat mode has been activated. It also has a low battery level warning. Charge back up between sessions with the USB-C charging port.
