TWSBI Vac700R Fountain Pen - Iris
Due to the nature of this material, each pen will vary in color, making each pen a bit unique. Please note we are unable to honor color requests.
The TWSBI Vac700R Iris comes with a vacuum filler mechanism. This fountain pen features a clear demonstrator body with rainbow-colored iridescent trim and a stainless steel nib accented with iridescent color. No two are exactly alike.
TWSBI's belief is that it is important to allow the user to disassemble and reassemble the pen and completely experience the traditional aspects of owning and using a fountain pen. These pens also come packaged with a wrench and silicone grease. Neither of these accessories are intended to be used immediately, as they are for long-term care and maintenance. Additionally, please use extra care if you choose to disassemble the nib and feed, as the feed is very fragile.
If you're taking apart this pen, note that the mechanism on the Vac700R removes out of the pen in a counter-clockwise direction. This is the opposite direction from other TWSBI pens like the 580.

Customer Reviews
Despite the beautiful colors & finish of the TWSBI Iris Limited Edition pen, for anyone looking for any stub tip wider than 1.1mm, they're out of luck. Although TWSBI lists a 1.5mm stub tip as available for this pen on their page, trying to select that option will show that unavailable, & confirmed after contacting both TWSBI, & JoWo, the nib manufacturer.
Sadly, those wishing for other sizes of replacement nibs than what is shown on TWSBI's page, will be left with scouring the interweb for compatible JoWo #6 compatible replacement nibs.
The TWSBI vac700r nib housing assembly may be proprietary, but I quite doubt that the JoWo #6 replacement tips are.
Having more options available, or at least, a list of compatible options, with source links, would have made this a perfect pen worthy of a 5-star rating.
I call them as I see them, & I am less than completely satisfied with this pen.
This is now my daily writer for almost everything. A steal for the price, fabulous!
This pen was so uncomfortable to hold I returned it un-inked. There is no step between the 10 mm grip and the 15 mm barrel. My thumb falls right on the threads and abrupt jump to the barrel. I also don't think the cap diameter includes the trim. It wouldn't fit in my pen roll like other pens that are listed at 16 mm. It's a shame because it's a beautiful pen at a great price.
This pen has everything: a huge transparent ink container, a large wet nib, a perfect balance and weight, it even looks good in a utilitarian yet original way. The only thing it doesn’t have is an aspiration to be an art or a status demonstration object. To get that kind of pen, you might want to spend a few thousand extra :-)
My first one took a high dive from my shirt pocket, and the cap broke on the tiled floor. I didn't think of contacting TWSBI to ask about a cap for this limited edition pen until a few days later.
My second one went AWOL.
My third one will begin wending its way to me on Monday morning. And I didn't buy three because I like spending money pointlessly. I bought three because it fills a definite need.
The medium nib glides across the paper as though on wings of thought. The nib starts imediately upon being bidden to do so. And the shutoff valve incorporated with the vacuum filler renders the pen virtually immune to burping and belching. It also closes off the ink reservoir from ambient air, which is a consideration for one using TWSBI's Blue-Black ink with its iron gall formulation.
Ambrea said, "I would definitely recommend this pen to fellow writers". I will second that recommendation unreservedly.
