These glowing radioactive syringes are a great item for dozens of twisted medical costumes from malpractice nurses to pandemic planning doctors - and mad scientists who create things like Frankenstein and zombies! The best part is that the glowing cylinder is actually a replaceable glow-stick, so it's good for years to come! Approximately 14.5 inches in length. This is great on its own, but could be even better with the other costumes and accessories available in our store!
