It's the last reader request ink for this week, and then we will move on. Let's take a look at Robert Oster Schwarze Rose. I purchased my bottle of ink from Pen Chalet. This ink is more expensive for a Robert Oster ink-the bottle is only 15ml, and cost $13.50.
Schwarze Rose is a dark green with a copper/rose gold shimmer. It's so dark I would maybe call it a green-black.
In large swabs there is a ton of shimmer. It looks to be the same shimmer that's used in the De Atramentis Pearlescent Copper inks.
Let's take a look at how the ink behaves on fountain pen friendly papers: Rhodia, Tomoe River, and Leuchtturm.
Dry time: 30 seconds
Water resistance: Low
Show through: Medium
On Staples 24 lb copy paper there was feathering and just a little bit of bleeding.
I used a Pelikan M400 White Tortoise with a vintage 400N nib. The ink had an average flow, I didn't have any issues with clogging.
Overall, it's pretty expensive for how much ink you get. It's well behaved for a shimmer ink, and I like that it uses a different shimmer instead of just gold or silver.
