Decorative Brass-Finished Key Ring & KeysA nifty desk decoration, or hang them on the wall of your. playroom. The detail is much, much better than that of our sand cast items. Antiqued brass finish. The ring is 3" in diameter. The longest key is 6, and the shortest is 4" PLEASE NOTE this, like all of our cast iron, is a reproduction. We have seen these being weathered and sold as actual antiques both on Ebay and in antique stores.
