The contemporary design of the "his & hers" key holder incorporates either a male or female form, which is raised up against its background forming an interesting design aspect and clearly identifying who's keys are whose!
The key holder is supplied with its own unique key, which is then attached to your own set of keys.
Just insert the key in the lock to keep your keys safe until you next need them.
There's no hook protruding from the wall, and your keys can't be bumped to the floor.
