This is a Yamata-gata stencil-dyed mini card made of washi paper, which I previously purchased at Ginza Mitsukoshi. It's a set of two cards. Although it's new and unused, I opened the package and took photos to check the contents. The reddish mark on the inside right of the black pig card is likely due to the orange pigment from the front transferring. I do not have any pets, and I do not smoke.
