"Empty" or unfilled CBD cartridges are essentially a blank slate for users to add their own CBD oil or e-liquid. They consist of the physical components of a vape cartridge—typically a mini tank (often glass or ceramic), a built-in coil and wick system, and a standard 510-thread connection—but contain no oil, artificial fillers, or cutting agents.
- Refillable: The primary purpose of an unfilled cartridge is to be filled by the user, offering a cost-effective alternative to pre-filled, disposable options.
- Customization: Users can choose the exact type of CBD oil (isolate, broad-spectrum, or full-spectrum), potency, and terpene profile or flavorings they prefer.
- Components: They are generally built with high-quality materials like glass and ceramic to ensure clean flavor and leak resistance when properly used. The standard connection allows compatibility with most 510-threaded vape batteries.
