These erasable flashcards are very convenient as you can reuse them indefinitely. Reusing your Flashcards has a positive impact on the environment and it saves you money! Besides these benefits, they also support a good cause. Correctbook donates one trimester of erasable writing material in Africa for every Flashcard package sold. Let’s improve the world together! You can use the flashcards instead of sticky notes. The little cards are ideal for studying concepts, words, or summaries. Or could you note the question on one side of the card and the answer on the other side? You can use our flashcards endlessly. Need a break?
