Each card has a hole in the top corner that can be fit with a ring or string to help with organization and storage. Additionally, each card has one corner that is shaped differently than the others. By lining up the non-rounded corners, the flash cards can quickly be faced in the same direction. When applicable, flash card sets include answers in small print on the reverse side of each card.
