I believe this was purchased about 40 years ago. The obi fastener is still in its original bag, so it's unused. (I opened it this time to check.) The string fastener still has its label wrapped around it, so it's unused. I don't know the name of the other large item, nor do I know how to use it, so I don't even know if it can be used with this one. Please understand that this item has been stored at home and has some age-related stains in several places, so please judge from the photos and only purchase if you understand this.
