These are the "Four Seasons of Ink" (Winter and Spring) purchased last year at the official Suzuka Ink shop. The photos of the items to be shipped are up to the third image, and the samples displayed in the shop are from the fourth image onwards. Retail price: 5,500 yen each Both can be ground on a regular inkstone. (After grinding black ink, wash the inkstone before grinding colored ink to prevent black from mixing in.) I want to sell these quickly, so I will consider price reductions if you have a desired price!
