Replacement stud/hardware Giant 21 gold thimble-looking 'crosshatch' style for Balenciaga. Bottom measurement is 3/4" for the giant 21. Hard to find- Balenciaga will NOT sale them to you, tell you where they get them, or even tell exactly what they are called (in my experience, anyway)... SALE IS FOR HARDWARE ONLY! NOT THE BAG! Thanks for looking!
