Anyway, here is the pen! I already have an Eco and know of its many benefits: the huuuuuuuge ink capacity, the demonstrator design so that you can see exactly how much ink is left, how lightweight it is in hand and its simplistic design.
One difference about the other Ecos and this one is the packaging. It came with this lovely cardboard sleeve which has the TWSBI logo in a rose gold hue. To me, this sleeve just looks that bit more elegant. The frosted plastic box is the same as always.
The rose gold accents complement the white elements beautifully.... If you like rose gold that is (I know it's not everyone's cup of tea!). The first ink I chose for mine? J. Herbin's Rouille d'Ancre. I love this ink but haven't had much opportunity to use it as work calls for a darker ink.
This is a beauty of a pen and it'll be a regular in my 'constantly inked' arsenal of pens. It currently has Robert Oster's Tranquility in it (an aptly named ink for the current times) but once that runs dry, who knows what I opt for next? All I know is, it will most definitely be inked.
