Copper is big & I have stocked up. This is yet another great looking one. It is a tad over 3/4" wide. Inside measures 6 6/16" with an opening of 1 2/16" so it will fit a larger wrist of say 8 to 9 with maybe a slight ajustment either way. Weighs 56.5 grams! The stampwork is real nice with a black rub inside them. It is hallmarked BLKGT...maybe one of the Blackgoats I would say?
