Brand new Authentic Valentino Rockstud Caged Flats

Selling authentic Valentino Rockstud Caged flats. Black patent leather. Size 38. Comes with Box and Dustbag. Never been worn, however both shoes have some marking/stain INSIDE on the heels, where I put in blister protectors when I tried them on. They left a residue/mark when I peeled them off.

I can also mail these shoes with two pairs of such blister protectors for free with this purchase (blister protectors seen in photo) Selling for $850, will ship, or can pick up in Toronto.
