There is not much to say I mean they are index cards that I needed for school - unlined on both sides. They are not live changing or anything but they did their job.
I only needed 50 but had to buy 500 so it will be quite some time before I need more. Still it is a good value if you need 500. Would have been nice to have a 100 pack instead of 500.
I use these cards for everything--we just created a "cook book" that is actually a 40 card set of recipes that can be used on their own and can go into a recipe file so easily.
