Regardless of how much I spend on pens with gold nibs and known names, nine times out of ten I still reach for a TWSBI.
The Swipe (got mine in Prussian Blue, medium nib) is their best! It so definitely in the running to tie for the smoothest nib I have. And that's right out of the box using the included cartridge. Speaking of which, this nice of a pampering workhorse coming with a cartridge plus two different converters? YES PLEASE! And these things hold a good amount of ink! It's gotta be more than a standard int'l cartridge.
I gotta say, if it wasn't for the price plus converters, I wouldn't have bought it. I hope this isn't an introductory price as that may kill the line. I look forward to more colors & design and of course more chunky TWSBI ink carts in tons of color, sheen and shimmer! They need to keep the snap lid and low profile clip as well.
