This is a set of 16 Cheki photos of Seiko Omori. I believe it includes photos from her time with ZOC. Many include signatures and comments, and some are decorated. Some also have messages on the back. I obtained these at live shows and events, and have stored them in sleeves in a dark place. There are no noticeable scratches or stains, but please understand that these have been stored by a private individual, so there may be minor imperfections. Please check the photos for the condition. No individual sales, and no price reduction, but I think it's a good deal because of that (calculated at 1874 yen per photo). Immediate purchase is OK.
