Anatomical models representing one or more anatomical structures of a human or non-human animal and related methods for demonstrating, training, promotion and sale of medical, cosmetic and surgical products or procedures. A working device is inserted into the anatomical model and used to perform a simulated procedure, thereby causing an indicator apparatus (e.g., a removable business card) to become perceptibly altered. The indicator apparatus may then be removed and provided a potential user, consumer or purchaser of the medical, surgical or cosmetic product.
