Well, here's one great option.
It includes 12 dividers and 100 index cards to get you started on all those homemade recipes, and it fits standard 5” x 3” index cards as well. Size: 5 ½” x 3 ½” and 2 ½” deep.
We love the look and the price. It's only $28 -- not bad, considering how much these boxes can run. It's a lovely and practical gift (for someone else or... yourself. Ahem.).
