You can either leave your Cypra needles and enjoy the natural patina or restore the gleaming copper sheen. The cloths are double stitched to hold up to the toughest tarnish. The 100% cotton outer cloth provides a gleaming lustre. The inner material is treated with LYKKE's trademark formula to remove tarnish and discolouration and restore lustre without scratching or removing the finish. The cloth measures 6x8in (15x20cm).
