I believe this is for Japanese sewing.

Has a Showa retro feel.
You might not find this nowadays.

It details Japanese sewing cutting methods and measurements, from adult to child sizes.
It fits within a folding screen style storage.
I don't know the specifics.
Please refer to the photos for size.
As it is an old item, there is age-related deterioration, but no tears.
We ask that only those who don't mind purchase.
We cannot accept returns or complaints, so thank you for your understanding.
