These are a set of fittings from a Hanwei Bamboo Mat katana.  

The fittings are used and show a lot of ware but they are still very usable and have a lot of life left in them.  The patina has come off a bit but there is no problem with the fittings.   If you are looking for replacement fittings then this gives you everything you need.  The tsuba, fuchi, kashira, and menuki are all included.
