This is a Pilot Grandy fountain pen. Blue lacquer is particularly rare and seldom available. Although it has a slim barrel, the lacquer coating makes it non-slip and I believe it is an excellent, very easy-to-use item. Operation has been confirmed. D1 refills are compatible. The ink will be removed before shipping. I used this for note-taking, but no longer need it as I have consolidated my notebooks into a smartphone app. I am offering it to anyone who wants it.
