Another original design from the Twisted Typist, these cufflinks are part of the new 'Mechanical Range', featuring personalised moving parts in silver and copper. The six handcrafted sterling silver rings on the cufflinks are designed to move around the inner copper core, and allow for discreet personalisation that is not easily read by others. Simply stunning and unique, these cufflinks are perfect for Father's Day, the Groom, Father of the Bride, a special birthday, or just because he likes something a little less ordinary. Handmade by Morgan & French in a jewellery studio housed in a quirky old Victorian Fire Station in Biggleswade, Bedfordshire. Every strike from the hammer will be seen in the jewellery adding to the unique handcrafted design.

This is not a fault, but a natural process of the metal. This process is natural, but some substances in our daily lives will speed the process up. Contact with soap, aftershave, food and even the natural oils on our hands can tarnish silver or copper quicker. Some people's skin is naturally more reactive to metals than others. To keep the metals looking good we recommend that you use a good quality jeweller's silver cloth regularly, as part of your jewellery cleaning routine, before the tarnish process begins.
