This is a set of 15 crane money envelopes. Bills folded into thirds will fit. The money shown in the photo is for demonstration purposes only and is not included. How about using them for celebrations or as envelopes to accompany letters? I am also selling other origami creations. These were folded by an elementary school student who loves origami. I tried to fold each one carefully, but there may be some slight wrinkles or misalignments. Thank you for your understanding.
