This is a lovely Nagoya obi
with flower and diamond on 'kikko ' (tortoise shell) pattern, which are dyed.
Background is dyed like 'washi' (Japanese paper) touch and it's mistaken for washi, because it looks very similar.
Textile is crisp cotton like paper.
It has overall discoloration.
There are other couple of flaws such as wrinkles of storage time (*It is indicated as folding line on the figure./*the 1st flaw photo).
Please check detail photos.
However, it still can be tied!
Please enjoy its touch and lovely design!
