It’s always very embarrassed when people who don’t
know if there’s anybody inside the bathroom, if they try
to pull the door, both the people inside and outside will
feel extremely uncomfortable.As a result, we designed a handle with red circle on the
outside part of the handle, if the user lock the door, the
handle will be pulled in and people outside can not even
try to pull the handle due to there’s no place.when the
people inside unlock the door, the handle will be back
to the place, so people can easily recognize if there’s
any body inside or not,and it can also help avoiding a
lot of awkward as well.
