Authentic. I'm selling these because I only wear black UGGs and don't use these. UGG MINI BAILEY BUTTON UGG Mini Bailey Button Size: 23cm Worn about 5 times, with no noticeable stains or damage. No stains. No sun damage. Still in good condition. Please refer to the photos for details. The colors in the photos may differ slightly from the actual product, as they were taken indoors.
