I don’t think they make anything like this one any more, either. Its product id seems to be B-101.
This is the usual composition book, sewn binding taped over the back, smaller than letter size. But it has graph-paper pages instead of lined. That’s nice. The big thing wrong with it is that the cover and back (same piece of board, wrapped around) are too flimsy for it to be useful in the situations when you need a notebook. It’d work fine writing on a desk.
This paper feels smoother and nicer than the paper in the cheap spiral-bound notebook, but it’s still too thin to use both sides with roller pens or fountain pens. But then I never use both sides in a composition book anyway, and rarely in a spiral bound even though they open flat.
