This is a Showa-retro origami set. There are 103 sheets. (I counted them, but there may be an error of 1-2 sheets due to the large number.) The sizes, from largest to smallest, are: 9.5 x 9.5 cm 8 x 8 cm 7.5 x 7.5 cm 5 x 5 cm Please check the photos for the patterns. They were stored loose, so some may have stains or damage. Please be aware of this. #origami #chiyogami #chiyogami
