The Moose are carved from stone and will last a life time. This is a set of two rocks with the design facing each other. The rocks comes with mounting hardware so all you have to do is replace your old drawer knobs with the new ones.The rocks comes from Lake Superior and has a very smooth surface. The Moose design is etched out from the rock and stand ABOVE the surface of the rock. The rocks are approx. 2" to 2 1/2" wide by 1" to 1 1/2" high by 3/8" to 3/4" thick. Each rock is truly "One of a Kind" as no two are the same shape
