Is this a joke?
Color: Cream, Size: Large, Color: Cream, Size: Large
Is this a joke? I just opened a package that was sold as new, but nowhere on the purchase did it say it was refurbished or used. It looks obviously worn, yet it was sold to me as new. This should have been given to me for free. There are permanent stains on it and fresh hair all around the neck area, and I don’t have hair — I’m bald. Please see the pictures and my video. I just opened the pack, and it looked refolded and packaged as if fresh from someone else’s laundry.

Great Quality Shirt That Looks More Expensive
Color: Cream, Size: Medium
This is my 2nd COOFANDY purchase for my husbands wardrobe! Really impressed with this Knit Button Down Textured Polo Shirt. The material feels soft and breathable, and the textured design gives it a more elevated look than a basic polo. It fits well, looks great dressed up or casual, and is perfect for vacations, dinners, or summer events. Excellent quality for the price.
