I used up the last few pages of the Muji lined notebook I’d been using for morning pages and started a new-to-me notebook, made by the Life Stationery Company in Japan. The company has been around since 1946 and makes a range of products. These notebooks are available at a variety of online retailers, but I hate buying notebooks sight unseen. Luckily for me, my somewhat local Japanese stationery store stocks them and I picked up the plain version a few months ago. I’ve mostly used plain paper for my morning pages and I like having lots of pages, but it’s a tradeoff between a bulky notebook (my Bindewerk was 144 sheets with hard covers) vs. easy to carry but fairly quick to use up (my Muji was 72 sheets with soft covers).
The Noble Note falls somewhere between the two in terms of expense as well. I have to import the Bindewerks from Germany and the shipping gets quite high, whereas the Mujis are available locally and are at the inexpensive end of the spectrum. You can pick up a Noble Note for about $15 through Amazon (my local store charges $15.95, which I think is pretty reasonable for a small independent retailer).
