Professional Simulated Blood is the creation of well-known industry makeup FX artist Rob Smith.
Professional Simulated Blood is the standard washable, mouth-safe blood which has been used in the industry for many years. Soap and warm water will remove it from most fabrics (and warm water alone in most cases). This blood is for use on skin and fabric.
Available in four subtly different shades; Arterial, Original, Venous and Aged. The difference in opacity is more obvious on dark surfaces.
