Blue week is coming to an end. Today's blue ink is Robert Oster School Blue. I purchased my samples of ink from Goulet Pens.
School blue is a dark blue with shading.
In large swabs on Tomoe River the ink almost looks a little bit more teal.
Dry time: 20 seconds
Water resistance: Low
Show through: Medium
On 20 pound copy paper there was just a tiny bit of feathering but other than that it performed really well.
I used a broad Pelikan M805 Ocean Swirl on Tomoe River paper. I really enjoyed this combo. The ink had an average flow.
Overall, I really like this ink. It has some nice shading and sheen, and is a nice color.
