Mainstays Grease Dispenser
I bought one of those grease pots the other day. I noticed it is stamped IMUSA on the bottom and handle. As it turns out, it is 12-cm diameter, measures a couple cm taller than the regular cup, and is 1.5-qt. I like it because it fits my DIY wood gas stove made from a 1-qt paint can, and the fact they are easier to find.
Also, the ridge that the strainer portion sits on appears to be located at the same place as the lip of the regular 12-cm cup. If you don't want the lid or strainer, you could probably cut on that line and sand it to make a normal 12-cm cup.
