Replacement Pen Nibs - TACHIKAWA Fine, Hard Chrome NO. 600EF JIS Mark Made in Japan Total: 40 nibs Condition: Unused, but stored at home for a long time. - 2 nibs have noticeable rust on the indented part in the center. - 13 nibs have some rust. - The other 25 nibs have no rust, but appear to have a mix of shine and dullness. I'm not familiar with replacement nibs, but I think all the nibs are clean and should work without problems. For protection, I will ship them in the green case they were stored in. Please note that the case has some stains that couldn't be completely removed. Shipping will be via Yu-Packet Post Mini. I am open to some price negotiation, so please feel free to ask.
