These are 100% authentic, purchased last year from the official UGG website. I only tried them on at the entrance and have never worn them outside. I do a lot of driving, and since they don't have a heel, I didn't use them, so I'm selling them. They are sold for over 26,000 yen on Buyma. I can upload photos of the actual item and the box later if you'd like. UGG Black Fur Slide Sandals. - Brand: UGG - Color: Black - Style: Slide Sandals - Material: Fur
