What is this in glovebox of 2014 S600?

You can re-fill it with anything you like, cologne, perfume, scented oils. The Mercedes scents are quite nice, but $100 or over.
I have refilled mine with a very fresh, non-invasive cologne, and it works great, but will say that since it is alcohol based, it only seems to last about a month. I understand that the OEM Mercedes scents or oils last 6-12 months. I keep mine on "high" or "max" (most scent distribution).
