Probably Smut book review journal inserts. These come in PS subscription boxes, but can be bought from their website alone as well. They also sell the journal! Pages will fit any A5 six ring binder, too. I have SIX packs of 10 that have never been open and 24 loose sheets. All in brand new condition without any marks/writing, bends, or creases. Come from a smoke free, mold free, dog friendly home (he doesnt hang out with my books).
