Cornish tin mine cuff links

This is a pair of Cornish Tin Mine cuff links. Approximately 18mm in diameter. They are fitted with a spring toggle that is suitable for double cuffs. They have been handmade in our workshop at Blue Hills from genuine Cornish tin that we have produced from tin ore collected under special licence along the Cornish coast at St.Agnes.
Each item is attractively boxed along with a certificate authenticity.
