These curlers had a flaw in the snap on each one. If you sleep in them, as advertised, your hair wraps around each snap and has to be CUT or PULLED OUT! When I contacted Kitsch, I was sent the link for the returns. Tried 3 different FedEx locations to drop off return and the QR code did not work. Again I contacted customer support and was sent the link for returns, which obviously doesn't work. Bad customer service! Terrible product!
