Let’s take a look at Diamine Ruby today. I purchased my bottle of ink from Cult Pens a few years ago.

The color:

Ruby is a medium unsaturated red.

Swabs:

In large swabs on Tomoe River paper the ink looks more matte and unsaturated.

Writing samples:

Let's take a look at how the ink behaves on fountain pen friendly papers: Rhodia, Tomoe River, and Leuchtturm.

Dry time: 40 seconds

Water resistance: Low

Longer writing:

I used a TWSBI Eco Blossom Red with a medium nib on a Taroko Enigma notebook. The ink had an average flow.

Overall, it’s a lovely red. It’s an interesting color and well behaved, but it lacks any shading or sheen to give it more depth. Since I love shading I don’t think I would reach for this ink often, but it’s a good basic red.
