At the beginning of 2019 Junji Sakai offered me the possibility of doing a lithography on a limestone base, it was my first lithography and I repeated the experience a second time with two new lithographs in smaller format. At the end of his Stone Letter Project, Junji Sakai made another proposal, also new to me, to make a box to store the lithography collection he had made in the framework of the project and in collaboration with artists. The box formally reminds of a stone with blunt edges and gray color, on its periphery white bands allow the registration of actions or list the content in the form of text or handwritten drawing.
