I purchased this here, but it's unused. No instructions were included. Please refer to the internet. Features: Can be dissolved in water to create simulated blood. Uses materials that are relatively easy to remove from clothing. Specifications: Type: Powdered simulated blood (10 pieces) The box may be taken out and folded, and then sent with bubble wrap for protection. Please understand. #Nurse #NursingStudent #Surflo #InjectionTraining #BloodCollectionPracticeKit
