Hello there! I am in the same situation, got some Tribal X supercritical co2 oil cartridge, Sour Diesel and Blue Dream, in NYC. I got them from a service that I've used before, and have gotten other similar cartridges in small cardboard boxes before, which have been fine. These seem to be similar but just another brand. Just like you, I have not found anything online. However, not all companies or cartridge companies have a site. But it is strange not to find ANYTHING. What was your experience with it? Did you try it? Are you ok? Any concerns? Would be great to know
Also, one thing I did notice is that cartridges had a colored line around the base, which did not match the color of the box. These lines were blue and others yellow, like a small piece of paper or tape around the cartridge itself (mostly for looks I guess)
