Due to the nature of the cuffs, it is inevitable that they will shed some feathers. Please do not worry, this is normal. If you would like to help prevent any excess shedding you can (from a distance) spray the feathers with hairspray.
Please do not machine wash or tumble dry the garment. The garment is hand wash only and please try your very best to not get the feathers wet. If the feathers do get slightly wet you can blow dry them with a hairdryer on low heat setting. (from a distance)
