Coil Building Kits: Comprehensive kits for advanced users who build their own coils. Typically include a variety of essential tools: ceramic tweezers, coil jigs (for wrapping coils), precision screwdrivers, wire cutters, scissors, and often a spool of wire and bag of cotton.

Custom E-Liquid Formulation: The service of creating a completely unique e-liquid flavor from scratch based on a client's concept or description. This involves R&D, multiple sample iterations, and finalizing a recipe that can be scaled for mass production.

Pod System Box Packaging: Higher-end cardboard boxes for pod starter kits. These often have a magnetic closure or sleeve and internal foam or plastic inserts to securely hold the device, pods, and accessories. The box design is crucial for communicating brand quality on a retail shelf.

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).

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.
