The koshira-e comprising a modern black-lacquer saya, a tsuka mounted with iron fuchi-gashira decorated with carriage wheels and grasses in gold hirazogan, gold menuki formed as dragons, and an iron Kyo-sukashi tsuba with branches and a bird in flight

Including, but not limited to the following:

The sword is in polish and is healthy.
The nakago has been over cleaned and all of the patina is gone.
There are a few light surface scratches near the hamachi, from contact with the habaki.
The corner of the habaki is bent and fits on the sword very tightly-- it can be removed but it is very tight.

Koshirae
The saya with some very light surface wear overall. There is a hairline surface lacquer crack to the lower edge of the koiguchi where it joins the saya.
The hardware all with surface oxidation and normal expected surface wear.
