These items were found while cleaning out my parents' house. They are colored paper that my mother had purchased for making paper mosaic art, and I believe they are over 10 years old. Size: Approximately 24.5 x 27 cm They are new, but please understand that they have been stored at home for a long time. I have attached a photo showing a stain on one of the sheets. Please note that even if you leave a comment or inquiry, priority will be given to those who purchase immediately. Returns and claims are not accepted. Price negotiations are welcome.
