Womens Size S / M HoMedics Pink terrycloth Slipper

Pair of Pink terrycloth slippers by Homedics w/massage!!! Gently worn; one has a very slight bit of darkening, but bottoms have virtually no wear; thong flip flop style; memory foam or similar inside; sides have zippers, and side button thing that turns on a massage. I don't know if its battery operated or what, or how you replace any batteries or if you even can. At the time of listing, both slippers vibrate. Since I don't know how they work, no guarantees how long they will last Size s/m
