Great little notebook
Style: COVER
I love these little notebooks. I have a case that they fit in just fine, along with a pencil. I use them primarily for my ham radio hobby for when I go to a park and need to record the contacts that I have made for the log.

Nice quality but could be better for the price.
Style: COVER
So nice quality but strange dimensions. There is no way to fold a standard 8.5x11" sheet of computer paper to fit neatly in this. So if you want to print out your own documents to take with you in this, this isn't ideal.
Has 2 internal pen slots and one on the outside. Has two business card slots but I wish it had more.

Pen Holder is Very Narrow
Style: COVER
Overall this item is effective for holding a Rite in the Rain 4.625" x 7" spiral side-bound notebook. There is no zipper on this so it does not seal. It has slots for a few cards and folded or smaller items can be tucked behind the notebook in the pockets that hold the covers. I haven't used it in the rain enough yet to know if those papers I have tucked in will stay dry. The description says a cell phone could be stored in those pockets as well. I haven't tried this, but my cell phone with a cover wouldn't fit. If you have a thin cell phone it might work, but I prefer to put both covers slid into the pockets so the notebook stays open easier when using it. The outer elastic closure is tight enough without being too tight. However, the pen holders are quite tight and small. They likely work well to hold in the Rite in the Rain pen that is narrow and smooth and possibly a narrow and smooth mechanical pencil, but they are too tight for my side click mechanical pencil. I could barely slide it in and when I tried to pull it out, the top half pulled off the bottom half of the pencil. It would also be a struggle to put larger pens in and out, but the elastic might stretch to fit those that are smooth over time. Despite not being able to use the loops for my preferred pencil, I chose to keep it.

Just what I was wanting
Style: KIT
Ordered to use a a gym notebook to track my progress. It’s holding up well being exposed to being shoved in a cramped gym bag repeatedly over the last 2 months. Sweat and water hasn’t hurt it and the cover seems to be holding up well. Still looks practically brand new.
