Disposable Vape Shells: The outer casing of a disposable device, typically made from PCTG or ABS plastic. They are designed for aesthetics (color, finish, texture), ergonomics (mouthpiece shape, hand-feel), and internal component housing. Different shapes and designs are a primary way brands differentiate their products.

Limited Edition Box Mods: High-end, often hand-finished mods produced in small quantities. They may use premium materials like stabilized wood, forged carbon fiber, or engraved brass. These are collector's items that represent the pinnacle of vaping as a hobby and craftsmanship.

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.

Mechanical Mod Clones: Unregulated devices with no electronic circuitry or safety features. They deliver raw battery voltage directly to the atomizer. Marketed to advanced enthusiasts who understand Ohm's Law and battery safety, these are often more affordable reproductions of high-end "authentic" mechanical mods.

Cotton Wicks: Specially selected and processed organic Japanese cotton. It is prized for its long fibers, purity, and excellent capillary action (wicking). It is supplied in large sheets, pads, or pre-cut strips for manual coil building or automated assembly in pre-built coils.
