I think this flask is super cute, and cheerful, and seems to me the perfect one to take to a soccer or rugby game, or to throw in a backpack before heading off on a hike. There's some wear to the yellow plastic cord (mostly a little darkening at spots where it crosses the wicker) but it still looks bright, and the wicker is in perfect shape. Plus, it has a matching yellow cap!
C. 1960s-70s, I'd guess. 5 3/8" tall x 2 3/4" wide x 1 3/8" deep.
