This is a Lipovitan D x Demon Slayer mini towel handkerchief set! It's a mini towel handkerchief that I received when I purchased a Lipovitan D product, and I've kept it at home unopened! Although it's unopened, I visually inspected it and found no stains, but this is a personal assessment. Therefore, I ask for your understanding as it's based on a casual inspection. I look forward to your purchase!
