Hand stamped keychains provide the best quality & aesthetic available. These large letters are hammered into the brass for a deep, permanent impression & filled with black ink for contrast & visibility. Hand-hammering gives them that slight human touch & uniqueness. These are at the sweet-spot of thickness to where you can't bend them with your hand but they're still light & inexpensive. Made from 100% brass with matching lobster clasps. Each tag measures 1 inch in diameter. These are perfect for initial tags, labeling needs, school supplies, etc.
