Whether for school or work, these key fobs are to be worn around the wrist or pocket for keeping track of keys, or holding ID badges. Key Fobs are all made with 100% cotton fabric printed on both sides, 3 layers, with interfacing in the middle to insure durability. We use a chrome 3/4" swivel snap hook for ease of use. All of the Key fobss are machine washable. When washing, wash in cold water and hang or lay flat to dry. Warm iron if needed. Key Fobs measure 3/4 of an inch (0.75 inches) wide, 14 inches long (28 inches all around) not counting the swivel hook at the bottom. Hook measures 1.75 inches long. We use the same fabric on our Lanyards and fase masks. Buy a matching set. Due to the handmade nature of the item, patterns placement may vary. Made in the USA.
