Just what the doctor ordered! These convenient combination writing implements look just like real syringes. The pen deploys when you depress the injector, allowing you to play both doctor and author at the same time! When you need to emphasize certain notes on your patient's chart (or your college study guide), you can remove the plunger top and reveal a handy highlighter! Price is per each pen. Comes in assorted colors (random selection - or specify colors in checkout comments - or purchase 6 for an assortment of colors). Makes a great gift for medical students or fans of novelty pens. Also makes an excellent stocking stuffer or party favor!
