LPN is short for Licensed Practical Nurse, which is boldly die struck and filled with red enamel. This is centered in a 3-D die-cast, gold plated caduceus. The caduceus is frequently used in the medical field, military medics and has become the unofficial symbol of medical professionals and medical associations. It will make a great graduation gift. Each LPN Caduceus Lapel Pin includes a standard clutch back and is individually poly bagged.
