Search and analysis of fingerprints is a well-known aspect of forensic science. When people touch an object, natural oils or sweat from the skin can be left behind, forming a fingerprint. Similarly, when a palm or toe touches a surface, it can leave identifiable traces. Each fingerprint is unique and never exactly the same as another. Fingerprint patterns are formed by ridges on the fingertips. Color: As shown Housing material: Cardboard Father and son, mother and daughter, or twins all have different fingerprint characteristics.
