Tunza Cards - Set of 25 Reusable Index Cards

If you use index cards for instruction, study aids, or general review, you don't want to miss out on these! Tunza Cards are blank, double-sided, 3" x 5" reusable index cards. You can write on these glossy cards over and over and just wipe them off with alcohol to use again. Sounds like a typical dry-erase board, right? Well, it's not; in fact, these cards don't really work well with dry-erase markers. You have to use a permanent marker like a sharpie to write whatever you want on the cards math problems, vocabulary words, letters, pictures, etc. You can use a dry-erase marker, but then the ink is prone to smear. If you use a permanent marker and wait for 20 seconds like instructed, the ink will not smudge or smear at all. All colors of ink seem to hold (and later erase) well on the cards. The seemingly everlastingness of the ink makes them much easier for hands-on use, especially for younger kids. Then, when you're ready to move on and use the cards for something else, just swab some alcohol over them and they're as good as new. Useful for every subject, these cards will come in handy again and again, so stop going through index cards like crazy and check out this reusable option. 25 cards in a pack. Rachel
