5 Card Badge Pocket Card Reference Set Keychain for Nurse Medic
This key chain comes from a series of cards that puts hard to memorize information at your fingertips.  Same as a standard badge (or credit card size;  2 1/8" by 3 3/8").  Each card is about half the thickness of a credit card so it won't weigh you down.  Please note badge cards are NOT removable.  Shipping from Scrubs and Stuff is combined so it is $1.99 regardless of how many items are purchased!
