This appears to be the first generation of the Apple-made Classic Buckle, sold from 2015 to 2018. Due to aging, a black ink-like or tar-like substance is seeping out from the leather, so please refrain from using it as is. There is a risk of staining your arm or clothing, and the stain may not come out. I contacted Apple, and they stated that this type of defect occurring over time, despite being a high-quality Apple-made leather band, is a normal characteristic. For the above reasons, this item is being sold as junk. Please use it for repairs or parts as you see fit. I am also listing another of the same item, which I believe has less damage. Thank you for looking.
