Various cracked sumi ink for calligraphy

This is calligraphy ink.
These are used items, some are broken and some have been used.
Many were intentionally broken to be used with an automatic ink grinder.
Would these be useful for those who use automatic ink grinders?

I have been practicing calligraphy for a long time, but I am decluttering. I am not sure about the market price, so I am listing them here, but please feel free to discuss price reductions or other matters.

Thank you for looking.
