The Leuchtturm A4+ Black Slim fits into our larger format A4 Leather Folio perfectly. Leuchtturm products are so well thought-out and high quality, we've been using them personally for years, so it was a natural pairing!

Here's why we love these notebooks:

- The Master Slim is larger than A4 and can hold loose sheets between the pages and in the expandable pocket without the edges protruding

- The A4+ slim format is large but not overly heavy/cumbersome

- They are thread-bound and lay flat when open, making it easy to read and write

- The paper is acid free, high quality and is compatible with a wide range of inks, so the ink won't bleed through

- They have a large gusseted pocket in the back to store loose sheets (perfect for keeping yarn labels handy)

- We love the numbered pages and blank table of contents at the front, allowing you the flexibility to organize it however you want

- They come with stickers for labelling & archiving, 2 bookmarks and an elastic closure

- The dotted pages are great for pattern sketching

These notebooks are currently only available in black and have a subtle T&M logo on the front cover :)
