Gradation marks in liter. It can nest TOAKS Titanium Wood Stove (STV-11), TOAKS Titanium 750ml Pot, 200g gas canister. It nests inside TOAKS Titanium 1600ml Pot with Pan (CKW-1600) 5. TOAKS Titanium 550ml D118mm Bowl (BWL-550-D118) nests this pot from outside.
I already have the 750mL cup/pot and wanted something a little larger to go with it so I could boil water and cook food at the same time without having to use the same pot. The 750 (inside its orange bag) nests quite nicely inside the 1100; I am able to put a 100g butane can inside of the 750 with that inside of the 1100. Plenty of room for other stuff. I'm still putting my pack together for a coyote hunt in the coming weeks, and am very happy with this setup.
I'm very happy with this purchase. The pot and pan are the perfect sizes for an ultralight hiker traveling on solo excursions. I also purchased a 750ml pot which nests inside the 1100ml pot keeping the footprint to a minimum.
