Today's ink review is on Robert Oster Plumb Nut. I've been in love with Robert Oster's ink because of their shading and sheen, so I'm still focusing on his inks this week. I purchased my bottle of ink from Pen Chalet. The bottle is 50 ml of ink.
Plumb Nut could be called a dark pink-it's not quite red, but it's not quite purple.
In the large swabs, Plumb Nut looks a bit more purple than it does in writing.
I love the shading ink drops show.
Feathering: Plumb Nut had no feathering on any of the papers.
Bleeding: Plumb Nut had no bleeding on any of the papers.
Ghosting: Plumb Nut had medium ghosting on Tomoe River, and low ghosting on the other three papers.
Shading: Plumb Nut had low shading on all of the papers, and no sheen.
Left to right: Robert Oster Australian Shiraz, Robert Oster Plumb Nut, and Robert Oster Maroon 1789.
Left to right: Diamine Maroon, Diamine Music-Strauss, and Sailor Jentle Grenade.
Diamine Music-Strauss is a little bit more red than Plumb Nut, and Robert Oster Maroon 1789 is a bit more purple.
In longer writing on Tomoe River, I noticed more shading. Towards the end of the page, the ink got lighter as my pen ran out of ink.
Overall, I liked this ink. I loved the shading it has, and it has an average flow. To me it is a "boutique" ink, not a classic because of the shading. Give it a try.
