Query: A helpful timesaver

These are for the old GRE, I believe a new set is coming out soon for the new GRE, so only buy them if you're taking the GRE before August.I found these flashcards to be a huge timesaver. I would not have been about to make 500 flashcards on my own. They have sample sentences, which come in handy fo learning the words, and the box fits nicely in my purse.
