Radius Settimo Cielo Blu, Diamine 150 Regency Blue, Diamine Forever Raven, Pilot Iroshizuku Sui gyoku
I just received a package from Fontoplumo and I immediately added the pen and inks it contained into rotation. While I already have a good amount of pens inked up, I really wanted to give the Radius 1934 Settimo Cielo Blu a try as soon as I got it. Not only is it a gorgeous looking pen, but I was also curious to see how it compares both the the vintage Radius fountain pen that I own and to my Leonardo fountain pens, as they are also the makers of the Radius.
Apart from the Radius the package contained two inks that I was interested in using as soon as possible, so I inked up a Pelikan M200 Petrol with Pilot Iroshizuku Sui gyoku and a Lamy AL Star with Diamine Forever Raven. The Radius got inked up withe Diamine 150 years Anniversary Regency Blue, a rich royal blue with moderate red sheen that fits the blue swirls on the pen body.

Comparing the Diamine Forever Raven to Sailor Black reveals that the Sailor is slightly darker than the Raven, but both are dark enough to count as proper black inks (and not dark grey or brown). They both have a bit of shading, but the Raven interests me as a waterproof ink, so I’ll be testing it with some watercolour sketches later on.

The Pilot Iroshizuku Sui gyoku isn’t what I expected. I was hoping for a more prominently green ink, but Sui gyoku is more of a turquoise than a green. I like turquoise inks so that won’t be a problem, but it means that I’m still on the lookout for an interesting, bright, readable green. The shading on this ink is delightful.
Diamine 150 Anniversary Regency Blue is a rich royal blue with some red sheen. It’s very saturated, especially in the Radius nib.

The Radius interested me not so much as a revival of the old Italian brand since the original Radius was a minor pen manufacturer, and I wasn’t blown away by the vintage Radius that I own. It seemed to me that the old Radius brand was busy making local copies of what Parker was doing at the time, which is understandable. However, Radius as a sub-brand of Leonardo is interesting since Leonardo have been hiking their prices lately but the Radius remains more affordable and offers resins and pen bodies that are just as attractive as what Leonardo has to offer.

I love both the blue, white and brown swirly resin of this pen and the art deco-ish band. It’s a big wide pen, like the Leonardo pens and Viscontis, but light and comfortable to use.

One tiny minus with my pen is that as the bottom part of the body tapers down, a smudge of brown resin was left, making it look like there’s permanent dirt on the pen body. Not ideal, but it’s something I can live with.

Here’s a writing sample of all three inks on Col-O-Ring cards.

And as a silly little treat I also bought two cartridge boxes of Lamy Pokemon ink cartridges. They are filled with regular black Lamy ink cartridges, which I knew, but is still disappointing – a teal and a red would have been better.
