These beautiful items are crafted by me, one at a time, they are composed of a quality printed image covered with a pure, crystal clear, domed glass cabochon that protects, and magnifies, the printed art underneath. The glass cabochons measure approximately 1 inch (2.54 cm) in diameter. Key rings are composed of a nickel-free plated alloy and are available in either silver or antiqued bronze finish and include a sturdy 1" (2.5 cm) diameter ring with lobster swivel hook attachment.
