Thank you for viewing! This is a set of 50 sheets of 15cm x 15cm Yuzen Chiyogami paper, one sheet each of 50 different designs. I'm selling some because I can't use them all. They are 15cm squares, but I cut them myself from larger sheets, so they are not as precise as commercially available products. However, I haven't noticed any significant discrepancies when using them myself. Also, Yuzen Washi paper varies in texture even when purchased from the same store. These are items stored at home. I don't have any special bags for origami, so I will put them in a slightly larger bag. Thank you for your understanding. ^ - ^
