The Bottom Line Up Front
Choosing between The Kind Pen’s Slim Wax Black and Slim Oil Black? You’re looking at two completely different vaping experiences packed into identical sleek designs.
Slim Wax Black is built for wax concentrates. This pen uses a ceramic chamber with dual ceramic rods and titanium coils that directly heat your wax concentrate. You get bigger, denser clouds and complete control over your dose—perfect for the hands-on experience of loading and vaping concentrates.
Slim Oil Black is designed for pre-filled cartridges. Pop in any 510-thread cartridge and you’re ready to go with buttonless, auto-draw activation. No buttons to press, no loading required—just pure grab-and-go convenience for your oils and distillates.

How Each Pen Fits Your Vaping Style
Using the Slim Wax Black
Here’s how the Slim Wax Black works in your daily routine: You’ll remove the mouthpiece to access that ceramic chamber, use the included packing tool to load a small amount of wax (don’t overfill—less is more for even heating), then reattach everything securely. Turn it on with 5 quick clicks, press and hold the button while you inhale, and you’re getting pure, flavorful vapor from those ceramic and titanium heating elements.
The hands-on approach means you get complete control over your session. Want a bigger hit? Load a bit more. Prefer lighter sessions? Use less concentrate. The ceramic chamber even catches excess wax for re-vaping, so nothing goes to waste.

Using the Slim Oil Black
The Slim Oil Black operates completely differently—and that’s the point. You’re dealing with pre-filled 510-thread cartridges that screw right onto the battery. No loading, no buttons, no prep time whatsoever. Just attach your cartridge and inhale—the auto-draw activation does everything else automatically.
This buttonless design makes it especially helpful for anyone with dexterity issues or hand mobility challenges. Plus, the standard 510-thread connection means you can use cartridges from any brand—THC distillates, CBD oils, full spectrum products, even nicotine e-juice.

Keeping Your Pen Running Smoothly
Slim Wax Black Maintenance
The ceramic chamber needs regular cleaning to prevent buildup and maintain that pure flavor profile. Use the included packing tool for loading to avoid mess, store the pen upright to minimize any potential leaks, and remember—don’t overpack that chamber. Even heating requires proper airflow.
Slim Oil Black Maintenance
This pen keeps maintenance minimal by design. Clean the 510-thread contacts occasionally for the best connection, store upright to prevent cartridge leaks, and keep that battery charged for reliable auto-draw performance. Use high-quality thin oil cartridges for optimal results.
