This ID holder is so cute! I'm only selling due to having too many. The colors are vibrant and will cheer up your patients, clients, and even your co-workers! I've witnessed it! 😁 It can be worn 3 different ways that I have figured out. Here are some general details. Clips securely to collar, pocket, purse, backpack, or tote bag, so identification is always handy and won’t get lost or left behind. Great for school/college IDs, work credentials, transportation passes, etc. Size Retractor length: Approximately 22" Holds standard/credit card sized ID (3.25” X2.25”)
