The Ari Knife Kit features a 510 thread which enables you to switch up to using an oil cartridge as well as a Type-C cable for faster charging capabilities. A notable trait that is favored with the Ari Knife Kit is its twisted voltage control that ranges from 1.8V to 4.2V, allowing you to easily swivel through your preferred temperature. The Ari Knife also features its preheat setting which will quickly let you scoop a substantial amount of wax.
