Again apologies, Mew, for such a late response. The answer is, yes. I prefer very simple designs and I have always loathed clips, not least because I don't put pens in pockets. One of the reasons for the late response is that, by chance, I managed to pick up a couple of Hakase pens recently, a Green Celluloid and, I blush to admit, a Tortoiseshell. I blush because I do have very serious qualms over flaunting the protected species bans but, as I am only human and weak, I couldn't resist. I am glad I didn't resist. The Green is a stub and I had reservations beforehand because it is not a nib that really suits my hand, but this one is so silky and light of touch that it has made me rethink my objections. The Tortoiseshell is a Fine, my preferred nib, and, well, it really is beyond compare.
You will enjoy meeting Yamamoto-San who is very charming. Enjoy your trip and I hope you find what you want.
