Need some sturdy paper for dividers, notes, or labels? This pack from Esselte Leitz is a solid choice. You get 15 sheets of blank index paper in a practical A5 size (that's about half the size of a standard A4 sheet). The paper is 'strengthened,' meaning it's a thicker, more durable cardboard with a weight of 100 grams per square meter (gsm). It's not flimsy at all—it's meant to hold up well as tabs in a binder or for signs that get handled often. The color is a neutral grey. These sheets are blank (no lines or printing), so you have total freedom to write, draw, or print on them with pens, markers, or maybe even in a printer (though the description mentions writing instruments specifically). They're pre-punched with 2 holes, making them ready to slot right into a compatible 2-ring binder or filing system. It's a simple, no-fuss product for getting organized at school, in the office, or at home for projects that need a bit more substance than regular paper.
