I'm late to this post, but I thought I'd pass on a bit of info.
I just bought a Maruman paper pad, called a "Report Pad"
50 sheet, B5, 7mm lined No margins, lined top to bottom. Like a small legal pad. $8.00 maybe? I chucked the receipt LOL
I purchased it at Kinokuniya Book Store, which is inside a Uwajamaya, an awesome Asian-food grocery store here in the PNW. They have locations across the country, but, not all of them have a Kinokuniya in them (Not entirely sure on this point.)
They have a huge selection of Japanese stationary there, including Apica, (including the premium notebooks talked about here) Campus, Maruman etc. And, they are expanding that section in the next couple of weeks, and will likely have even more variety.
It strikes me as a bit pricey, but, I can walk in and buy immediately, know exactly what I'm getting, and support a local retailer, of sorts. And, they have a ton of other cool stuff there. Including Moomin, Domo and Maru.. LOL
tvradio, if you are still looking, I can snatch up a bunch of pads for you if you want, and send them to you. If you are in a semi-hurry, it's close to where I live, and I don't really need much of an excuse to go back there LOL
If anyone else is looking for Japanese stationary of any kind, post here or message me, and I'll have a look next time I go back there (probably a week or two, after they get the new stuff out for sale)
They also have hard to find brush pens, and some Sumi-e supplies.
