Scale cubes used for taking pictures and photographs of meteorites, geology, plants, or anything where you need an object in the picture as a reference for size and/or direction. They are made of Tungsten Carbide, a very hard dense material. Properly cared for they should last a lifetime. They come in un plated, PVD (18 K gold), PVD (Black which is made of Titanium Nitrile and Aluminum) You can get them as either shiny (polished) or matte (brushed) finishes. The letters are Laser Etched T on top and 1cm B on bottom N, E,W, and S on sides. All letters have a dot showing the bottom of the letter. Scale cubes are used for a variety of purposes, used in geologic (meteorites) pictures taken in the field, in a photo studio, and as a reference in photographs where the size of an object would not otherwise be known. (Geologist often used shovels or rulers in the past but scale cubes are now being used more often in taking pictures of small objects) They are often used where the faces can be aligned to match compass bearings. The different faces (T-top, B-bottom, N-North, S-South, E-East, W-West) can also be used as an indication as to which side of the object the viewer is seeing
