By nature, each piece is unique! These keychains made from German hazelnut wood are refined with laser engraving (also in Germany). The wood is cut into slices with bark, and the keyring is attached with a sturdy metal eyelet. The slices have a diameter of approximately 4 to 5 cm and a thickness of 0.6 cm. As it is a natural product, there may be slight variations in size, color, and shape. Material: Hazelnut wood with metal ring and metal eyelet Dimensions: Wood slice: approx. 4 to 5 cm Ø approx. 0.6 cm thickness Keyring: 2.5 to 3 cm Ø
