What a great way to keep the cards from spilling all over your desk or table. These mini cards are great for small notes, or study aids. Cards are produced with white index stock, and are ruled on one side. The size of each card is 3″ x 2.5″, and there are 200 cards per tray. Each tray is polywrapped. Made in Indonesia. Category Description for Mini Index Cards: These were a hit with our office staff-and certain staff's children! At 3x2.5", they are a perfect size for single-term or scripture verse memory cards, improvised game pieces, alphabet and number learning; you name it. One side contains 1/4" ruled lines (white cards include an additional top margin) and a top line in red. Opposite side is blank.
