The Modern Dog Tag Flying Monkey Edition is made in the USA. These limited-edition, handcrafted modern dog tags were cut, shaped, and polished by Plane Pieces Inc. from actual airplane propellers. These pieces are created from the authentic parts of airplanes that have been at altitudes of a mile and more. Each tag measures approximately 1 _" in diameter and comes with an oversized hole. Each is uniquely crafted, and no two pieces are alike. The sexy necklace in highly polished aluminum comes with customizable features, such as a 24" stainless steel ball chain that can be cut to your preferred length.
