Black Shirt, White Surprises

I ordered a black T-shirt with a printed design, expecting a clean and high-quality finish. Unfortunately, upon arrival, I noticed white, non-removable residue on the fabric. It’s disappointing, as it takes away from the sleek look I was hoping for. The print itself is fine, but the visible marks make the shirt look unfinished or even defective. I’ve tried removing them, but no luck. For a new item, this shouldn’t be an issue. If this is a production flaw, I hope it gets addressed, as otherwise, the design and fit are solid. But right now, it’s not what I expected.
