This is refill ink specifically for Shachihata Name 9 stamps. I purchased this about 5 years ago and have kept it stored, unused and unopened. I am selling it because I have no use for it. I stored it in a dark place, so the quality is probably not degraded, but since about 5 years have passed since the purchase, the possibility of degradation is not zero. Please be aware of the above, and consider purchasing with no claims and no returns.
