To enhance realism, MST’s “Decayed Flesh” scent may be sprayed on the wound. Made from movie-quality silicone rubber, MST’s ulcers are highly realistic, durable, reusable, hypoallergenic, and designed to be used right out of the box. With no further makeup required after application*, these wounds are designed to allow trainees to identify and treat ulcers and sores of all sizes.
