Montblanc Albert Einstein is a limited edition ink from 2013. It can still be found but at slightly silly prices. Many thanks to Chris Stafford for sending me this sample.
Here I am doodling the Inkling.
This is a very wet ink but dries quickly. I see a hint of yellow in this, which I actually quite like. I’ve not seen anyone else mention a yellow tint to Albert Einstein (the ink, that is) so maybe it’s just me.
