Hallmarked, solid, 100% recycled sterling silver button cufflinks. These silver buttons have a matt frosted detailing in the centre, a highly polished rim and come with sterling silver bullet back and toggle (swivel) links. Cufflinks come in a beautiful anthracite and black ribbed paper gift box with an inner velour cover. Silver options include a complimentary Edge Only "Maintain Your Edge" silver polishing cloth. Hallmarked sterling silver stamped 925 Sterling silver jewellery naturally develops a darker patina over time due to oxidation. It is a completely normal and natural reaction known as tarnish (silver reacts to moisture and chemicals in the air such as sulphur, as it does to chemicals and moisture on our skin from body sprays, lotions and perfumes). Avoid storing in humid environments such as the bathroom. Silver jewellery remains at its shiny best when worn daily or kept in a dry, air-tight box or bag. To clean any tarnishing, simply polish with your Edge Only silver cloth to regain a silver finish. Regular use of a silver cloth removes light tarnish and inhibits re-tarnishing, prolonging the original sparkle of your silver. If you don't have a silver cloth to hand a microfibre cloth or eye glass cloth is ideal.
