Since MSR® (Mountain Safety Research) introduced its first mountaineering stove in 1973, the creator of backcountry gear has offered quality and reliable products for cooking while outdoors. For 2018, MSR introduces the PocketRocket® 2 Mini Stove Kit, built specifically for ultralight minimalists attempting to go farther and faster with less on their backs.
Interesting decision to rest the cup under the pot. Surely it can get a bit dirty over the time?
My MSR Windburner's cup stacks the same way, but it's less exposed compared to this one.
I also do have a similar setup: Esbit Cookset 585 (- solid fuel burner) + Alpkit Kraku + Sea to Summit X-Mug. Comes to 258g. Slightly smaller volumes, though.
