Review: Robert Oster Plumb Nut


Robert Oster Plumb Nut

A few days ago, I tried out my sample of Robert Oster Plumb Nut. Aside from the little dab of ink on the cap, I didn’t really know what to expect because I’m not sure what a plumb nut is. I used my Sailor Sapporo Progear Slim with a medium nib and (after getting acquainted with the color a bit more) a Lamy Studiio with a 1.5 mm nib. Right off the bat, I like that it’s a pleasant old rose color. It’s a mellow kind of pink, a bit dusky, with a slight hint of purple. It has beautiful deep pink shading, and no sheen. When I first tried it with my Sailor pen, it felt thin, almost watery. It doesn’t bleed or go all over the place, but it felt watery on paper as I wrote, so my nib felt like it’s gliding on the surface of the paper. I reversed my nib to see how it would look like in an xf nib (or maybe closer to a needlepoint) and it flowed quite wet too. I also used it with a 1.5 mm Lamy nib to see how it will hold up with a wider nib.

The nib never ran dry, and it showed off the gorgeous characteristics of the ink. Even if the ink’s consistency felt watery, the saturation is not too light. It darkened a bit after drying, but remained a pleasant pop or color on paper. It also dried up pretty quickly at about 10 seconds or so using the medium nib on Tomoe River paper. It’s also not water resistant.

Here are a few close ups of the writing sample:
