Some things are just made to fit inside other things.

Don’t get any ideas, sicko. We’re talking about your keys.

The reason you can never seem to find them? They really just want to be in a lock.

The folks at UncommonGoods figured this out — and offer his and hers key holders. The wall-mounted receptacles, inspired by the symbols most often seen on bathroom doors, provide the perfect resting place for your keys: a lock-like receptacle positioned, appropriately or inappropriately enough, just where you’d think. (You would.)

Sure to induce snickers from guests — as well as a few birds-and-bees queries from the young ’uns.

In which case, you know just what to say.
