Durable Plastic Tanks: Utilize advanced polycarbonate or PEI plastic materials for the tank section instead of glass. These are virtually unbreakable from drops, making them ideal for clumsy users or active lifestyles. However, some plastics can be susceptible to cracking from certain "tank cracker" e-liquids (e.g., strong citrus, cinnamon).

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.

Child-Resistant Locking Packaging: A specialized and often legally required packaging service. This involves manufacturing packaging that meets specific safety standards (like US FDA's CRP requirements), which typically involves a mechanism that is difficult for children under 5 to open but manageable for adults.

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.

Open System Pod Kits: Centered around a reusable battery device paired with refillable pods. Users purchase their own e-liquid separately, allowing for vast customization of flavor and nicotine strength. This system offers a lower long-term cost per puff and attracts users who enjoy experimenting with different e-liquids from various manufacturers.
