I came up with this idea while I was shopping during the coronavirus crisis and I was forced to touch handles of any kind : fridges, drawers, payment terminals, buttons in the elevator...
I designed also an holder for preventing cross-contamination.
Of course this doesn't replace the fact that you still have to wash your hands often.
Also don't forget to disinfect this object every day with alcohol !!!
Take care, stay at home and stay safe.
