I bought a two-pack at Nishimatsuya. It said something like "Heattech" on it. The white one has a yellow stain on the back. It's either from a mandarin orange or ketchup. Overall, there's a feeling of use, pilling, and fuzzing. I am a private seller, so I may have overlooked something. Also, I have a dog, so I will be careful, but there may be some dog hair mixed in. Please consider this before purchasing.
