Shortfill E-Liquids: Large bottles (e.g., 60ml, 120ml) filled with nicotine-free e-liquid, leaving a "short" space in the bottle. The user adds a separate small bottle of concentrated nicotine (a "nicotine shot") to achieve their desired strength. This is a popular regulatory workaround in regions that limit bottle size for nicotine-containing liquids. |

Top-Fill Tanks: The modern standard for tank design. The top cap swivels, slides, or lifts open to reveal large fill ports, making refilling e-liquid quick, easy, and mess-free. This is a critical user experience feature that has largely replaced older bottom-fill designs. |

High-PG E-Liquid: Formulated with a high ratio of Propylene Glycol (PG) to Vegetable Glycerin (VG) (e.g., 50% PG / 50% VG or 70% PG / 30% VG). PG is thinner, provides a stronger "throat hit," and carries flavor more effectively. It's the standard for Mouth-To-Lung vaping and nicotine salts. |
