Glass Chimneys & Tanks: Borosilicate glass components that form the central tube (chimney) and the e-liquid reservoir (tank) in rebuildable tanks and sub-ohm tanks. They must be manufactured to exact dimensions to ensure a perfect seal and are prized for their flavor purity and resistance to heat.High-Puff-Count & Shisha Disposables Catering to heavy users and flavor enthusiasts, this category features devices with large-capacity e-liquid tanks (often 10ml+) and powerful batteries designed to deliver puff counts exceeding 5000. They are frequently paired with rich, complex "Shisha" or dessert-inspired flavor profiles that are popular in specific international markets. The emphasis is on lasting power and a intensely flavorful experience, making them a premium offering within the disposable segment for dedicated consumers.https://cbu01.alicdn.com/img/ibank/2016/232/186/3727681232_1441267458.220x220xz.jpgLow-Resistance Pods (for DTL): Designed with a coil resistance typically below 1.0 ohm. These pods allow for more power to flow to the coil, producing larger vapor clouds and a warmer vape suitable for Direct-To-Lung inhalation, where vapor is drawn directly into the lungs.Glass Bell Tanks: The classic tank design where the main chamber is a clear glass tube. This allows users to easily monitor e-liquid levels. The glass is resistant to flavor staining but is vulnerable to breaking if dropped, so they often come with replacement glass sections.
