These 8.5 in. x 11 in. blank sheets have three 8.5 in. x 3 2/3 in. micro perforated hangers with detachable cards measuring at 2 in. x 3 2/3 in. The detachable cards are located at the bottom pre perfed as well to make separating simple. They can be used in many different ways, but the most common is to tear off the card at the bottom and give it to a parent/guardian as a wallet-sized student ID.
