Pen+Gear Narrow Ruled Mini Binder Filler Paper, 5.5" x 8.5", 100 Sheets

I should've grabbed more than one pack while I was in the store. While the paper looks thin, there is no ghosting while writing. As an added bonus, it takes to fountain pen well with no bleed-thru. The only slight issue is drying time; only problematic for speedy writers. What I Use It For I got this because I needed filler paper for my A5 6-ring binder. The paper is narrower and slightly taller than the current paper that's being used. Despite the 7-holes, you can't use it as-is for a 6-ring binder. The hole spacing is 20-mm between the first and last set of 3-holes and 13-mm from the center hole to the sets of 3. I wound up re-punching the holes so the paper can be used in my A5 6-ring binder and added some hole reinforcement labels. It's still nice paper but it would be nice if hole-spacing information were included with the product description.
