Miffy Foldable Bag - Unused Travel Bag

I bought this last year for my daughter's school trip, but it was not used.
It's a size that fits in a carry-on case suitable for a child's 2-night trip.

It was sold unfolded when I purchased it,
and I folded it myself, so although it's unused, it's not folded as neatly as it would be if it were new.

I've lowered the price accordingly.
(It cost around ¥5,000.)

I think it can also be used as a shoulder bag,
but I didn't notice at the time of purchase, and it might not have come with one originally. I don't remember as I was in a hurry.

Due to a busy schedule, I cannot measure the exact dimensions.
It will be shipped in simple packaging.
