I purchased this from an online store. Because of the camouflage pattern, I didn't see any noticeable stains, but as I am not a professional, there may be oversights. I would appreciate it if you could understand this. I believe I purchased it about three years ago. My memory is vague, and I've forgotten which online store I bought it from, but it was expensive, so I don't think it's a fake. However, I don't have the qualifications to authenticate it, so I cannot definitively say it is genuine. Please understand that I cannot provide a 100% guarantee due to the prevalence of counterfeit goods. I can add photos if you would like to see specific parts of the item. I will sell it to someone who can make their own judgment. I will sell it to someone who understands that it is a used item. The packaging will be simple and compact for shipping. Please also understand that wrinkles may occur.
