I found these in two sizes in Powerbooks. The Derwent Sketch notebooks seem to have been a holiday gift favorite, as the branches I visited (Shangri-la Mall and near Greenbelt 4) had only one or two left.
The smaller size is a Moleskinealike, with a rough suede-alike cover. The paper is thick white card stock. It feels thicker and sturdier than the one used inside Moleskine Sketch notebooks, although more “toothy” to the touch. Paper with a little texture holds on to colored pencil and graphite better, and this isn’t at all a surprise given what Derwent’s really known for.
A first stab at copperplate resulted in feathering. I’ll try another nib-ink combination tomorrow.
