My Personal Pens: Namiki Emperor Vermillion

The Namiki Emperor is a great pen, in every sense of the word.  It’s a giant ebonite pen, which is then lacquered with urushi.  The nib is Namiki’s #50 – and it’s enormous and a little springy (contrary to the modern Emperor nibs, which are stiffer, as I understand).  A behemoth, this eyedropper-filled pen with a one-way shutoff valve holds about 6 ml of ink – so I can use this for weeks without having to re-ink it.  If you are interested, I have also recorded a full review of this pen.  This beautiful pen was a gift from Azizah, which makes it all the more special.
