3-Book Set Past Ledger, Kinran Torinoko, 5-inch, Undated, Brown (Orange)

Thank you for looking.
This is a set of 3 unused Kakochō (Buddhist memorial registers) with no dates, made of Kinran Torinoko Japanese paper, size 5寸 (approx. 15cm).
The color is a brown/orange hue.
(All 3 books are the same color.)

I purchased these in bulk several years ago but never used them.
Kakochō can be used in place of ihai (memorial tablets) and should be treated with respect. They have been stored at home.
While the boxes may have some dullness,
the registers themselves are unused and in good condition.
One book has been taken out as a sample for the photos.
Currently, similar items would cost over 5,000 yen each. I have set a price for this set, so please consider it.
Thank you.

* A Kakochō is a family genealogy (register) that records the names (secular names), kaimei (Buddhist posthumous names or dharma names), death dates, and ages of deceased family members.
It can be used in place of ihai and should be treated with respect.
If you have too many ancestral ihai and they do not fit in the Buddhist altar even with a kuridashi-ihai (multi-name memorial tablet), it is recommended to consolidate them into a Kakochō around the 33rd or 50th memorial service.
