MSKKSM 3 x 5-Inch Ruled Index Cards, 300 Count, Six Neon Colors

Students and teachers looking to sort study material by topic can use these cards to give each subject or category its own color.

The 3 x 5-inch format also suits quick lists and notes that need to stay portable, rather than a larger sheet or notebook page.

If your priority is organizing information visually, the six-color assortment offers a different approach from using one-color cards or keeping everything in a notebook.

Key specifications

• Size: 3 x 5 inches
• Count: 300 cards, with 50 in each of six colors
• Colors: Red, orange, yellow, green, blue, and purple
• Paper: 160 GSM
• Lines: Narrow ruled lines with 7 mm spacing on one side, the reverse is blank
• Item weight: 0.42 kg

The lined face gives handwriting a guide for definitions, vocabulary, or short task lists, while the blank back leaves room for a quick sketch or diagram. The six colors can help separate subjects, project stages, or priority groups without adding labels to every card. The paper is described as suitable for pencil, ink pens, gel pens, and highlighters, with the product information noting resistance to marker bleed-through. That can be useful when a card needs both written notes and color emphasis, though results may depend on the writing tool and how it is used.

Everyday use

For exam prep, a student could assign a color to each class, write a prompt on the ruled side, and use the blank reverse for a diagram or answer. The same format can hold a grocery list, recipe note, or language-learning term when a full notebook feels unnecessary. The cards are described as compact enough for backpacks, planner pockets, and desk drawers, so they can be kept with the materials needed for a study session or daily planning.

Customer feedback highlights the vivid colors and flexibility for sorting flashcards, and some buyers say the cards work with different kinds of ink. Impressions of the paper itself are mixed: some find it good, while others compare its feel to construction paper and describe the cards as thin or flimsy. If cards will be handled repeatedly, that difference in expectations is worth weighing, buyers seeking a more rigid feel may prefer a heavier card stock. Worth considering if color-coding is more useful to you than having every note in one place.

What’s included

The set contains 300 ruled index cards: 50 each in red, orange, yellow, green, blue, and purple. Each card is 3 x 5 inches, with lines on one side and a blank reverse. This quantity supports building several color-coded study sets or keeping a supply for household lists and notes. It is a fixed assortment, so the colors are divided evenly rather than supplied as a larger quantity of one preferred shade.

Should you buy it?

Choose this set if you want a portable card format, six colors for organizing separate topics, and a ruled writing surface paired with a blank side. It offers a more visual alternative to plain, single-color cards for study systems, lists, and short notes. It might not be a great match if you specifically need firm, rigid cards: customer impressions of thickness and quality differ, and some describe them as flimsy. The choice comes down to whether color separation and the two-sided layout matter more than a sturdier feel.
