This is a 9-piece set for a 7-year-old, including an obi ita (stiffener), obimakura (obi pillow), datejime (under-sash), koshigimo (waist cords), sanjū-himo (triple cords), clip belt, magic belt, and a mesh obimae-shin (obi front core). This set includes the small items needed for wearing a fukuro obi (formal obi). I bought this new for Shichi-Go-San (a traditional Japanese festival for children aged three, five, and seven), opened the package, but didn't use it because the person who did the dressing lent me their own set. It's in very clean condition.
