I received this from someone in the company. I don't remember exactly when I received it, but I think it's been several years. I've kept it carefully, so it's in good condition. Based on my own research on the Keikyu Corporation official website and Mercari, I haven't found any other examples of this same pattern of towel handkerchief, so it may not be widely available or may be a non-sale item. Please ask any questions in the comments.
