Note: Our black bands that engrave to white and rainbow somehow got mixed together. We are unable to determine which is which. Our dual tone Apple Watch bands look like ordinary watch bands but they are a dual layer silicone especially for engraving! The washable silicone band for Apple Watch is soft, flexible, lightweight, latex-free, comfortable, breathable, dirt-resistant, waterproof and sweat resistant. These are totally perfect for laser engraving using your laser engraver. See photo to see the color they engrave to. Bands come blank. We are not engraving watch bands at this time.
