This is a genuine Apple silicone band. It's an Apple-made Apple Watch band in the color Midnight, size S/M, for 41mm models, so it's compatible with 38mm, 40mm, and 41mm cases. It came with the watch when I bought it, and I've only worn it once or twice, so it's in excellent condition with no scratches. - Color: Black - Material: Silicone - Compatibility: For Apple Watch - Size: Although the exact fit size is unknown, it is compatible with standard Apple Watches. - Design: Smooth surface finish and a hole design Thank you for looking.
