Cufflinks with a miniature landscape with three mountain peaks, pine trees and a moon. Designed for mountaineers and nature lovers. These cufflinks embody the elegance and spirit of nature. Measurements: 15 mm x 15 mm Materials: Glass and brass. They are durable and easy to maintain. They do not rust and the glass cleans with mild soap and water. If you're concerned about the environment, you'll be happy to know that the glass in these cufflinks comes from old buildings in Barcelona. You'll take a little piece of this beautiful and vibrant Spanish city with you. Glass and enamel are fused at high temperature to form a solid piece with a fascinating depth effect. The surface of the glass is glossy and not easily scratched. The glass piece has been fixed with industrial epoxy adhesive to a brass base with a dark, shiny metal coating that leaves no stains on the fabric. The twins are articulated for ease of use. They are delivered in a small cardboard box. There may be slight variations in sizes and color tones due to manual work.
