Fingerprints / Cleaning device

Fingerprints
Fingerprints

"Handprints" is a hand cleaning tool that allows the user to squeeze the liquid stored in the porous material on its surface to release, leaving the user's handprint to indicate that the area has been contaminated. "Handprints" support the filling of liquids, and when most areas receive contamination, the user can restore the contaminated area by refilling the liquid. This design is designed to reduce human-to-human contact in an outbreak and to simplify the hand cleaning process.
