You've got a card box full of half-finished notes, study prompts, and that one speech you keep rewriting. The cards are flimsy, the colours clash, and nothing lines up when you slot them in. These fix that. Five Esselte system cards, ruled on both sides, cut to 127 x 76mm so they drop straight into your existing Esselte card file box without wobbling. The board is 200gsm – thick enough to survive a week of desk-to-bag-to-desk without curling. You get white, pink, green, yellow, and blue in one pack, so colour-coding your to-dos, flashcards, or meeting notes takes ten seconds instead of a trip to the stationery aisle. Grab the pack, sort your system, get back to work
