The MJ Arsenal Gemini is a dual-chamber mini dab rig — two connected chambers that work together to give you extra filtration and cooling in a still-compact package. It's one of MJ Arsenal's more interesting designs, and the double-filtration actually shows up in the smoothness of the hit. More complex than a single-chamber rig, but still easy to use and maintain.
A solid upgrade if you've already had a basic mini rig and want something with a little more to it. Clean glass, tight build, and hits that justify the name.
