This is a "Full Bracer" measuring 9 1/2"" wide and will fit a wrist size from 6 inches to 8 inches around. (Send me measurements for custom sizes if needed.) I have 2 different classes currently available: weapon class and science class. Every piece is different and uniquely stamped with lots of clockwork designs, metal plates, and/or wire and tubing, but each style will have specific properties. The heavy 6-7oz leather is then finished with your choice of dye and silver or brass hardware.
