HD Blood is engineered in cooperation with leading special make-up effects designers, HD Blood is the perfect imitation of human blood for the high definition camera. Path tracing, opacity and color gradients are optimized for sensitive cameras and result in a very realistic blood effect in direct observation. It is the perfect choice for small stages and casualty simulations. Flowing speed is reduced slightly for better manageability. HD Blood is washable from most fabrics and does not stain on skin after washed off with soap and warm water. Do not use in the mouth area and do not swallow.
