Custom Label & Logo Design: A full-service graphic design offering. The manufacturer's design team creates the brand's visual identity, including the logo, color scheme, and typography, and then applies it to all packaging, ensuring a professional and cohesive look across the entire product line.

510 Connectors: The industry-standard threaded interface that connects a tank to a mod. It consists of a threaded outer ring and a positive pin insulated from the outer threading. Manufacturing these to precise tolerances is critical for universal compatibility, reliable conductivity, and preventing e-liquid leakage onto the mod.

Freebase Nicotine E-Liquid Lines: The traditional form of nicotine used in e-liquids. It provides a stronger throat hit, which many experienced vapers enjoy, and is typically used in lower strengths (0mg, 3mg, 6mg, 12mg) for sub-ohm vaping.

E-Liquid Box Packaging: Smaller cardboard boxes designed to hold a 30ml, 60ml, or 120ml glass or plastic e-liquid bottle. They provide protection from light (which can degrade nicotine and flavor) and offer ample space for branding, ingredient lists, warnings, and government-mandated tax stamps.

Open System Empty Pods: Refillable pods designed for open system kits. They typically consist of a plastic housing, a mouthpiece, and a rubber stopper. Users fill them with their chosen e-liquid. These are the primary consumable for open systems and are often sold in multi-packs.
