The Spoon Sisters Key Hiding Rock can keep a secret. Sold by the gift-giving website The Spoon Sisters, the Key Hiding Rock is a great present for the suburbanite. And, as the site cleverly acknowledges, it is, "not recommended for apartment dwellers."
Buying this rock ends the tradition of hiding the spare set of keys under a mat. Instead it provides a safer option. By pulling out the red cork, the user can fill the rock with a key or a small set, depending on the size. The Key Hiding Rock craftily stays incognito amongst the landscape. It may work so well that the user might have to remember where they ended up stashing the rock.
