During his extensive work in the Motion Picture industry Ken Diaz realized that commercially available bloods were simply not realistic enough for the critical eye. Ken Diaz also realized that Make-up, Hair, Wardrobe, Special Effects and Prop Departments all had numerous specific blood needs, that were not being met. To meet these demands, Ken has developed, the "K.D. 151 Blood Line". This line features twenty of the most commonly asked for types of blood, meticulously color matching the characteristics of actual human blood at its various stages. These products work well when used individually and in combination.
