These have the same Shield Knot symbol as seen in the wax seal collection. One order contains a pair of cufflinks. The cuff links look like the impression that the seal makes, so using these as seals is not recommended. Off-round shafts prevent rotation and keep cuff links from slipping out by accident.
Any symbol you see in the seals and signet rings collection can be converted to cuff links upon request. Please send a private message if interested.
This symbol is also available as wax seal.
