Respiratory Therapists, pulmonologists and nurses will love this colorful and cute "lung squad" badge reel! What better way to show your style and humor than with a fun badge holder! Design measures 1.5" across the button top. Each badge reel is very lightweight, so it won't pull on your work uniform, scrubs or clothes. A retractable nylon cord rolls in and out of the reel, allowing you to easily swipe your ID card holder when needed.
