blue index cards

Available sizes include standard 3" x 5" index cards and smaller mini cards at 3" x 2.5".

You can get plain blue cards and assorted-color packs. Assorted packs explicitly list violet, blue, canary, green, and cherry.

The cards are made of paper and the product descriptions specify an uncoated paper finish.

At least one option highlights curved corners designed to prevent scratching your fingers.

Mini cards measure 3" x 2.5", compared with standard cards at 3" x 5"—the mini format is half the size of the standard card.

Descriptions call out that some ruled cards are acid-free, the material is paper, and the paper finish is uncoated.
