This is a set of Sanrio's "Kero Kero Keroppi" pocket envelopes, with 4 designs and 19 pieces in total (the upper left pocket envelope in the first image has 4 pieces, and the other 3 types have 5 pieces each, for a total of 19 pieces). I opened them to show the contents. The bag in the second image is torn, so I will put them in a different bag for delivery. Please refer to the ruler in the picture for the size. They are the type that can hold bills without folding them. As far as I can see, there doesn't seem to be any significant damage, but since they are old, there may be damage that is not visible from the outside (the bags have damage such as tears and stains). To avoid any problems, I recommend that those who are concerned about the condition do not purchase them.
