One collar core, one half-length undergarment, two collar stays, two undergarment fasteners, two obi-shita (under-obi) pieces, one obi board, one heko obi. These are the items shown in the first photo. 10-piece set. Tabi socks are not included. There may be other things I've missed, but there are no noticeable major stains. I have washed them, but there are wrinkles.
