Just the little Cap that screws onto your coil and comes with the Starter Kit but is not included with the Replacement Coil Packs - and that folks have lost or damaged - we got em!
PLEASE NOTE: Many Yocan parts including coils are NOT interchangeable between different models. Please try to choose correctly-matching parts for your pen, as it is difficult for us to try to correct an order after-the-fact wiith considerations such as; highly-likely ownership of multiple devices, delays in communication, and avoidance of delivery delays. "Evolve", "Evolve Plus", "Evolve Plus XL", "Evolve D", "Magneto" and "Loaded" (etc.) parts and pens are generally different items and not interchangeable - please carefully select the correct accessories/parts to match your specific vaporizer - Evolve / Pandon parts for Evolve (and Pandon) pens, Evolve Plus parts for Evolve Plus pens (with some overlap with Magneto and Evolve Plus XL), Evolve Plus XL parts for Evolve Plus XL pens, Evolve D parts for Evolve D pens, Loaded parts for Loaded pens, Cerum parts for Cerums, and NYX / Torch parts MOSTLY work for both NYX and Torch dab devices, etc.
