Set of 4. Immediate purchase is OK. Items marked with ★ have stains like those in the second photo, and those marked with ♡ have a slight fold at the bottom right corner, as shown in the fourth photo. Also, although they have been stored in a dark place, there may be damage and deterioration on the corners, etc., so please purchase only if you understand this. 10th Edition, 9th Edition, Soichiro Sorihashi
