This $76K “Birkinstock” Sandal Is Made From Real Birkin Bags. It’s almost too perfect: the “Birkinstock” is a Birkenstock sandal made out of a real, authentic, insanely expensive Birkin bag. The luxurious sandals, which are priced at between $35,000 and $76,000 — as much as the bag itself — were made by Brooklyn creative collective MSCHF.
