Unused Benibana Sumi (Safflower Ink) Choshun-en in Wooden Box

This is a solid ink stick from Choshun-en, called Benibana-boku (commonly known as O-hana-boku).
As the company has closed down, this item is no longer available.
The size is 1.5 cho-gata (approximately 1.9 x 1.2 x 8.1 cm).
I have another one of the same item, so please let me know in the comments if you are interested (I will offer a discount equivalent to at least the shipping cost).
I have set this price as I am unsure of the market value. Please feel free to discuss it with me.
