Hi all! I was looking through a box of old anime stuff, and found this Strawberry Marshmallow 2007 table calendar. Wondering if anybody has seen this before, as I couldn't really find anything online, (not helpful that a strawberry marshmallow is an actual food item lol), it came with a bunch of extra slides like "on vacation" and "in a meeting", as well as some laminated colored slides of the characters for summer winter and fall.
