These are a little too thin to be great as index cards and are better as note paper. I found some thicker blank index cards elsewhere which I am using instead but I am sure that these index cards from Staples can be used in other ways
I needed to make Flashcards for a first grader at my school. These work well and the price is right. Should last through the remainder of the school year.
We use these cards to save copies of obituaries from the local newspaper. These copies neatly filed in small file boxes serve as an important research tool for family historians and it is simple to make a copy for anyone who needs it. Just the right tool for the job.
Cards are of good quality. They pass through my printer fairly well with one paper jam in about 500 cards. They look good after printing. Unruled cards are getting hard to get. Most stores have quit keeping adequate stock.
