Instruction Manual Printing: The production of multi-language instruction manuals and safety guides. These are legally required in many markets and must include clear diagrams, usage instructions, warnings, and company contact information. They are often printed on low-cost, thin paper and folded inside the product box.

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.

Mesh Wire Strips: Thin, flat strips of resistive metal (often kanthal or SS316L) perforated with a fine mesh pattern. These are the core component of mesh coils, offering a large surface area. They are supplied on large spools for automated cutting and assembly into coil heads.

Organic/Ethically Sourced E-Liquids: A premium segment where the ingredients (flavor concentrates, VG, PG) are sourced from organic or ethically responsible suppliers. This is a key marketing point for brands targeting health-conscious and environmentally aware consumers.

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.
