I'm having a tough time finding paper that I can write on comfortably, I'm used to 4-hole standard A4 sized paper, as this is very common in Europe. I like how I could easily slip in printed problem sheets, book excerpts, or journal articles into my notes and have everything neat and flush, ready for temp or permanent binding, either in a ring binder or spiraled together. However all I can find in the states are 3-hole 'college ruled' notebooks that don't sit flush with A4 paper, which is driving me a bit nuts. To the point where I'm just using printer paper on a clamp-tablet for consistency. Is there any reason A4 sized notebooks are so hard to find in the US? Are school and college students forced to use this bizarre 'college ruled' scale paper for any particular reason? I've checked online but most of the options are import stores with pretty inflated prices.
