For kids and adults alike, there is perhaps no better study tool than index cards. But repeatedly buying new stacks of index cards only to use them once and then throw them away can be both wasteful and costly. That's why a mother of three middle-school students created Tunza Cards.
With Tunza Cards, a person can write on the cards and - when the information is no longer needed - wipe the text away and use them again! Best of all, writing on the cards won't smudge, smear or disappear until a person intentionally wipes it away. Why go through a forest of trees when you can just use one set of Tunza Cards?
- Designed for use with Sharpie or Bic permanent ink pens
- Simply wipes off with rubbing alcohol; non-smearing and non-smudging
- Environmentally friendly
- Made in the USA
