Semicircle shaped silver cufflinks. When put together, they form the growth rings of a tree. The jewellery part is 100% recycled silver, e.g. from old X-ray films. The other parts are around 70% recycled silver. The rest of the silver is otherwise ecologically and responsibly sourced. The cufflinks are handcrafted in Hakaniemi Market Hall in Helsinki. Size 20 x 10 mm. Handmade products will have slight variation.
