## Description

Kokuyo Systemic Synthetic Leather Cover Notebook, with One A5, B 6mm Ruled, 28 Lines, 50 Sheets, Twin Ring Edge Title Notebook, Navy Blue, Japan Import (NO-V685B-DB)

Review: Initial impression: best notebook cover I've used - I have been searching and searching for just the right notebook cover for my journal and have been unable to find one to suit all of my needs until now. I have ordered several from desertcart only to find them lacking some functionality that left me overall dissatisfied. This one really seems like a keeper. I am going to go into a whole lot of detail here because everything is in Japanese and I'm going to try to answer some questions I had before I received this. I use an A5 notebook by Tumbitri Meri for my journal which I 100% recommend. I like to use fountain pens and the Tumbitri Meri stands up so much better to the ink than the Lechturm I had prior because it has 120gsm pages compared to Lechturm's 80. But I digress only to make this point: my notebook is thick. Super thick pages and 220 of them. I will be purchasing a shorter one once this one is full, but in the meantime, it's been hard to find a notebook cover or organization system that fits it. This cover has not one, not two but three separate places to hold a notebook, and two of those places give you the flexibility to add a top-bound or side-bound notebook, so if you like to use junior-sized legal pads, you can keep them alongside a journal or book. I currently have my thick notebook, the notebook that the cover came with (which btw, is a nice little notebook with a clear PVC front cover and thoughtfully designed pages), and a junior-sized legal pad to boot. And it all tucks up into a nice little (if thick) package with the exterior elastic band. My journal has a pen holder in the spine which I can thankfully still easily use while it's in this cover. I use a Pilot Decimo, but since I don't normally drop that kind of money on a pen, I can get a little anxious about it when I take it out in the wild. Tucking it into its holder on the spine of my notebook which is now safely encased on the interior of the spine of this cover eases my anxiety. I have a Sharpie pen inside the built-in pen holder as well, but this is on the outside edge of the cover and is a bit more precarious for my fanciest pen. Folded completely open, the left-hand side has a PVC pocket that can be used for a top or side bound notebook, the middle has a large pocket that can hold another notebook or supplies. Then there are three credit card slots that I have small stencils and washi tape samples in but could also be used for business cards, gift cards, etc. The right side is the fold-out leaf, which is a PVC pocket that serves to hold my notebook and could also be used for some loose papers and such. It's also capable of holding a top-bound notebook. I have wrapped the elastic on the back cover of my notebook around the fold-out for a more secure fit. There are ribbon bookmarks on the fold-out flap and between the left cover and the center portion, to help you keep your place no matter where your notebook is. They're a little superfluous for my purposes but I could see them being very helpful if my journal didn't already have 3. Both covers feature fabric pockets that could be used to hold maybe writing utensils or stencils or post-its or other supplies; I can even store my e-reader or phone here. The elastic closure on the cover is 2-3 times thicker than the one on my notebook so it seems sturdy and capable and handling the thickness of all this stuff put together. I got the navy, which in the picture looked like it had a bit more green to it, but this is a true navy color. It's handsome, though, and professional looking. And it seems sturdy and well-made. In addition to my use, I would recommend this to anyone who keeps more than one notebook (like one for work, one personal), or a journal and a planner and would like to keep them together, business professionals taking notes on meetings, artists, and people who like to take notes on their reading, lefties and others who like top-bound notebooks. Or really anyone, based on my initial impressions at least. This one is special.
Review: Excellent Cover for the Cost - I bought this case as a cover for my Hobonichi A5 Cousin. I’m very impressed with the quality. It is a very sturdy case. I love that it came with a notebook because one can never have too many notebooks. It does not smell like some faux leather cases do. It is very versatile and exactly what I would expect to receive from the Kokuyo brand. Overall, I would say that its value exceeds what I paid for it. It is a very well put together cover/planner system. And of course, my planner fits in it perfectly. I have it in the clear pocket since I have a clear cover on my planner. With the clear cover the planner would not fit in the back pocket, but it would if I removed the clear cover. I’m not sure if it will continue to fit well as my planner chunks up throughout the year, but if you are someone who does not add much ephemera or stickers to your planner this is a great option for a cover.

### ⭐⭐⭐⭐⭐ Initial impression: best notebook cover I've used

### ⭐⭐⭐⭐⭐ Perfect fit for my Leuchtturm1917s
*by A***W on February 21, 2024*

I've been getting back into handwritten notes recently and wanted a cover that I could take from notebook to notebook for years. I think these might fit the bill! I bought both the A5 and "Semi B5" sizes and am finding them really nice. The material feels great for the price and it's got plenty of pockets. My one struggle has been getting the right notebooks to fill these things (I'm sure we are all familiar with the pain of notebook sizes not being exactly standard). I should say, first, that the included twin ring notebooks are of surprisingly good quality for how light they are. I don't write in Japanese so I'm not sure how the ruling is intended to be used, but it's clean and unique and might be good for margin notes. Not wanting to break the bank, I started out with some cheap notebooks which fit okay, but a bit snug. I had an Amazon Basics Moleskine knockoff that fit perfectly in the A5 size, so that may be a good fit if you don't mind the cheaper quality of that notebook. In the end, I decided to get some Leuchtturms, as they seem well-liked by the journaling community. I am happy to report that the A5 medium Leuchtturm is a perfect fit for the A5 notebook cover, and the B5 composition Leuchtturm is a perfect fit for the Semi B5 notebook cover. You can fully utilize both notebook flaps with these Leuchtturm notebooks. I have seen some people put a 3rd notebook into the Semi B5 size, but I don't think that would be possible with Leuchtturms. Hope that was helpful, as I was having a hard time shopping for the right notebooks. Anything with the same dimensions should suit your needs perfectly.
