This is a pack of 6 x 38mm (1 1/2") antiqued effect D rings.
They are an extremely sturdy fitting when used for luggage such as bags and cases and a great match for our antiqued effect buckles, but we advise that they should not be used on dog or horse wear, as these are wire formed steel fittings rather than cast brass.
38mm / 1 1/2" is the internal measurement along the flat side of the D Ring.
