Hello Kitty origami. Retro cute Kitty-chan, Mimmy-chan, and Kitty-chan's mother's illustrations, etc... They're so cute, I haven't used them. All the designs are different and cute. (Some of the sheets in the two types had the same design.) Made in 1999 and 2002, they are over 20 years old. The back of the package shows signs of aging, such as discoloration. The contents were opened to take photos. I think they are in good condition. They have been stored at home for a long time. Thank you for looking.
