I have used these 4 x 6 cards for a long time for all kinds of things. Lately though I use them for taping recipes on them that I want to save. This way it is easy to file them and find them.
Reviewing paper products might seem kind of "wrong". These index cards worked as you expect them to work. I use them in an epson ink jet printer and so far they have been working wonderfully. They have not gotten stuck in the printer at all These are not the 1st packs that I have bought over the last 10 years
