Ruled cards

Start with the space you need and how you’ll use the notes. This range includes three sizes: 7.5 x 10 cm, 15 x 10 cm, and 15 x 20 cm, all at 180 GSM with 50 sheets each. The 7.5 x 10 cm cards are ideal for pocket notes, the 15 x 10 cm cards give more writing room for formulas or outlines, and the 15 x 20 cm cards suit longer summaries or meeting points. Choose based on your typical writing space and portability.

180 GSM is a heavy, durable stock that resists bending and ink bleed, ensuring clean, double-sided writing. The range uses heavyweight cardstock praised for durability and the ability to handle ballpoint pens, gel ink, and highlighters without showing through to the back. This makes the cards reliable for frequent handling in classrooms, offices, and study spaces.

For students, the 7.5 x 10 cm cards are perfect for quick flash notes and pocket study guides. For professionals, the 15 x 10 cm size provides room for concise outlines and formulas, while the 15 x 20 cm cards work well for meeting minutes and project summaries. Each size balances readability with portability to fit different study and work styles.

Keep the cards in a sturdy holder or binder to prevent curling and keep notes organized by subject. Store dry and away from moisture to preserve paper quality, especially for the larger formats that can warp if damp. Using labeled index boxes or rings helps you quickly locate the right card during study sessions or meetings.
