Wool & Wire stitch markers are handcrafted in the US from copper-core wire dipped in .999 pure silver. Created with genuine fresh-water pearls and faceted crystals, these stitch markers are both a luxurious knitting accessory and a perfect accent to the Wool & Wire Silver Necklaces. Each jewelry piece in the collection can hold up to 7 markers. Since each stitch marker is created one of a kind, colors may vary.
