Silicon Seals & Gaskets: Small, precisely molded silicone components critical for preventing leakage. They are used in tank threading, fill ports, pod connections, and around glass sections. The quality and design of these tiny parts are paramount to the leak-free performance of any vaping device.

Fruit Flavors: The most extensive category. Ranges from single-note flavors (e.g., Strawberry) to complex, multi-layered blends (e.g., Mango Peach Pineapple). Requires skilled flavor chemists to create authentic, non-candy-like fruit profiles.

Button-Activated Pod Kits: Require the user to press a physical button to activate the heating coil and produce vapor. This offers more control over the vaping experience, allowing for pre-heating and preventing accidental activation in a bag or pocket, though it is slightly less intuitive than draw-activated models.

E-Liquid Bottles: Often called "unicorn bottles," these are long, slender LDPE plastic bottles with a needle-nose tip for easy, precise refilling of tanks and pods. They are a fundamental accessory for anyone who buys e-liquid in large bottles or decants their own mixes.

PCB Boards & Chipsets: The brains of the device. Ranging from simple boards in disposables that manage basic firing and charging to advanced, programmable chipsets in mods that control every parameter (wattage, temperature, curves) and provide extensive safety protections (short-circuit, overheat, reverse polarity).
