Hello Kitty origami. Retro cute Kitty-chan and Mimmy-chan, with different cute designs. (Some of the sheets had the same design out of the two types.) Made in 1999 and 2002, these are over 20 years old. Although unused, 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.
