All are on blue marine vinyl on front and back. Details are machine embroidered. The designs are done in a varieties of colors: yellow, black/white/gray variegated, and black/white mixed.
I have black vinyl ones with different colors here.
They have been hand cut and finished with a D-ring lobster clasp or Split ring and rivet. They measure 3 1/4" long (not including hardware) and 3" at its widest point.
