Brass bangle with knotted leather and black silk wrapped on both ends.
1/8" (3 mm) wide.
Available in black, blue and natural leather.
Available in two sizes:
Medium: 2.63" (6.7 cm) inside diameter (will fit most), or
Large: 2.88" (7.3 cm) inside diameter.
These run large, I'm afraid they won't work in very small hands.
