Index cards are two-hole punched at the top and perforated in the middle so you can have standard-size index cards or mini cards to help you study and present. Simply flip to the next card to read or quiz yourself. Included 1-1/4" binder ring keeps all the cards together no matter the size. Cards are ruled on one side with a red margin line at the top and are made of durable cardstock. 85 lb. cards are rotary cut for uniform height and made of 7.5 point commercial stock.
