It's probably remaining stock or reject of old Agfa Ortho 25, a reproduction film.
Selling this for 5 bucks per roll as a whatever-bird-special-effect hipster film is a ripoff for sure. Use ANY low-speed film and push it and you get the same contrast. Put a blue or green filter on the lens and you get an "ortho" look.
