Designed to allow trainees to identify and treat ulcers and sores of all sizes. Each highly realistic ulcer is durable, reusable, hypoallergenic, and made from movie-quality silicone rubber. Use right out of the box - no further makeup required after application. To enhance realism, a "decayed flesh" scent may be sprayed on the wound (not included, (SB50237M)). Apply with silicone or manikin adhesive. Dark skin color.
