What is a key characteristic of fingerprint hinge lifters?

A key characteristic of fingerprint hinge lifters is that they have a hinge on one side. This design feature allows the lifter to be more efficient in collecting latent fingerprints. The hinge enables the user to easily lift and apply the lifter to a surface without disturbing the area around the print, thus reducing the risk of smudging or damaging delicate latent prints during collection.

The other characteristics do not accurately describe fingerprint hinge lifters. They are typically not oversized, which would make them cumbersome and difficult to use. While some lifters may be made of paper, this is not a defining feature when considering the effectiveness of their design. Additionally, they are certainly not made from glass, as such a material would not allow for the needed flexibility and adherence required to properly lift and preserve a fingerprint.
