Stacking all three on my shelf looks surprisingly tidy for something meant to hide papers, and the lids pop off without a fight every time I need to grab a document. The A4 size is spot on, so my folders slide in flat without bending or sticking out.

Finally, a set of boxes that actually fits A4 files without bending the corners - the lids slide on and off easily even when my hands are full. Having all three in the same size means I can stack them on my shelf and they look neat instead of mismatched.

I was skeptical about stacking them, but the lids fit snugly enough that I can pile all three on my desk without worrying about them slipping. They hold A4 folders perfectly, and my papers finally have a permanent home instead of living in random piles.
