Just found it yesterday. Its a Tudor notebook available in A4 and A5 called Eco Notebook. Its a recycled paper product so I feared the worst when I picked it up. But the apper, an ivory colour with red ruling, felt good. I bought the A5 for $3. It has a hard cover with a red spiral. Paper behaves very well with a range of FPs including my Parker duofolds, Lamys. snorkels and a couple of others.
I will play some more and add to this thread but right now this is one of the finds of the year for me, especially at the price. They say you can also get office pads in the same stock but I haven't found them as yet.
