Beautiful colour and buttery smooth
Excellent packing from onlinemantra
I am surprised how dark this ink is. It's more blackish than bluish, which is a good thing, because most blue-black ink tends to be either a greyish blue or mostly greyish. This is definitely a blackish blue. It flows smoothly. On the papers I tried, I did not find any shimmer, a mild sheen maybe seen on some papers.
The sheer feel of holding this Green Fantasy is Mind Blowing...
Proud possession
Kaweco Sport Iguana Blue is nice looking pen with excellent writing performance. This colour is my favourite. Love this pen. ThanksOLM.
Excellent
Great ink, Color, flow
The Packaging is Excellent. The Quality of the Cartridges is Exceptional and the Colour is uniform. Really Love the Product as well as Service.
Smooth writer
This is my third Vanishing Point—and there's something undeniably charismatic about this fountain pen from Pilot. I had previously tried the fine and medium nibs, but as they say, third time’s the charm. The broad nib, in particular, is one of the best I’ve ever used—smooth, expressive, and an absolute joy to write with. Easily one of the best purchases in my fountain pen journey so far.
My only regret? Not choosing the broad nib sooner.
Great bright, water proof ink. Brightest blue ever. Bleeding is minimal, you can use regular 70gsm paper if using with a fine (European) or medium (Asian) nib. Only a light shade visible on the other side of the paper. Feathering is zero.
It’s permanent and so magnificently bright color
It is fluid and smooth. Dries quickly and looks smooth.
Awesome service.
Perfect Ink match for my Dioplomat Viper blue guilloché!
The pen writes excellent. Out of expectation...
