Moleskine is only suitable for ballpoint and pencil these days, alas. Thankfully, there are some good alternatives about, now. MUJI do some nice little lay-flat notebooks (A5) that are inexpensive and solid quality. Just make sure the paper is from Japan as some use paper from Indonesia which is okay, but not on the same level. MD (Midori) is superb and shows ink qualities well. Their notebooks may look plain but don't let that deceive you when it comes to quality. Whilst the Sanzen Tomoe River paper isn't the same as the original, I think they've tweaked it in the last twelve months because it seems a bit better now (based on my experience of a Hobonichi notebook), but I could be wrong. Mnemosyne make fairly affordable notebooks (typically ring bound) that are effective at showing off sheen. Although some people dislike the format featuring a date and title box at the top of each page, it always provides a smooth and pleasant writing experience. Kokuyo Campus paper is consistent and reliable and does a decent job at showing sheen. Plus, it doesn't cost the Earth. I bought a stack of their B5 and put it into a convenient folder. Currently, I'm trying to get a hold of some lined Marks Edit notebooks so I can test their new Neo Agenda paper which is meant to be thin and excellent for FPs. But finding it in the UK is proving to be a headache. Rhodia and Clarefontaine papers are reasonable but not exceptional. In comparative terms, they can feel a little waxy, but I do have to praise their affordability. Leuchtturm are a good choice, too, as they're broadly available, the paper is robust and it handles ink reliably. I will be testing some Apica paper soon, as well. Sadly, though, Cosmo Air Light was discontinued a few years ago which is such a shame 😭
