The material used to create this cast metal ring is lightweight aluminum with an aged bronze layer with black patina above. The two lenses fold out at angle of 180 degrees and then slide apart, forming a small telescope. If you want a closer look, the large lens doubles as a magnifying glass. In the central section of the ring, right under the lens when folded, is placed small magnetic compass. It is forwarded to the client in a stylish tin suitable for gifts..
