The ACE & MM 2g disposable vape pen (empty only) is a dual-brand style chassis designed for B2B buyers who want a premium 2-gram–class shell with solid engineering and easy private-label options. As empty hardware, it ships with no oil, no nicotine, no THC inside—just a sealed body, integrated lithium battery, 2g-class tank, and a matched ceramic heating core. The form factor is built for long runtime and smooth draw, with a compact silhouette, clear branding zones, and enough surface area for compliance marks, batch codes, and OEM artwork. For licensed fillers, the value is simple: a ready-to-fill 2g platform that combines the visual pull of an ACE × MM collaboration with practical details like defined wetted-path materials, stable resistance, and carton packing designed for bulk orders, sampling, and repeat production runs.
