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: KOKUYO Delivers Again - A Great A5 Notebook for Work and Beyond - Okay, so I just got my hands on this KOKUYO Systemic notebook, and honestly, Im pretty impressed right out of the box. As someone whos always jotting things down, whether its for work meetings, planning, or just random ideas, a good, reliable notebook is absolutely essential. off, the gray synthetic leather cover is really nice. It feels substantial and premium in your hand, not flimsy or cheap like some leather-look products can sometimes be. The color is a classic, professional gray that looks great sitting on a desk or tucked into a bag. Its A5 size, which for me is pretty much perfect big enough to write comfortably without feeling cramped, but not so big its a pain to carry around. It really strikes that sweet spot for versatility., the paper feels really smooth to write on. Ive tested it with a few different pens gel pens, a standard ballpoint, and even a finer-tipped marker and so far, no bleed-through or significant ghosting on the other side, which is a huge win in my book. Nothing worse than trying to write on both sides and seeing the previous pages writing trying to peek through! The pages also lay pretty flat when you open it up, especially after you break it in a bit, which is crucial for comfortable, uninterrupted writing. really appreciate the systemic aspect of it it just feels like a very well-thought-out and put-together notebook. The binding feels sturdy and like itll hold up to being opened and closed a lot without pages trying to escape. I can easily see this becoming my new go-to for everything from daily journaling to important meeting notes or even just sketching out ideas., if youre in the market for a solid, professional-looking notebook that feels good to use and holds up well, this KOKUYO A5 is definitely worth checking out. Its got that reliable quality youd expect from the brand. Really happy with it!
Review: Fit everything in one compact folio - I was genuinely shocked when I came across this padfolio. I'd just spent two days struggling to find a folio in this size that's cheaper than the "genuine leather" ones, not up charged for personalization, and not from an obscure brand without enough reviews or longevity to prove its worth. When I finally spotted this, I could hardly believe it. A true A5 padfolio, not a 5x8 claiming to match A5, and it fits two notepads, side or top bound, with additional pockets for loose papers and business cards and such. This things fits so much in such a tiny and affordable package! I put a 5x8 notepad on the left side and an A5 pad on the right, both top bound. My Shaeffer 100 rollerball fit inside the pen loop on the right. The outside pockets on the front and back both fit the A5 paper when removed from the notepads. The plastic pocket that holds the pad on the right also fold out to give easy access to a set of 3 card pockets and the larger internal pocket to hold loose pages. If you're looking for a folio that's more than just a cover, you found it! And the maker, Kokuyo, has been around for over 100 years, so you don't have to risk your money on some new no-name seller.

### ⭐⭐⭐⭐⭐ Initial impression: best notebook cover I've used
*by Z***Z on September 1, 2020*

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 amazon 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.
