The do have them
- the question becomes if they are food-safe or not. They'd need to be drilled if they were usable. You could also rig something up with saran wrap and tape to seal off your carboy - it'd be ghetto as hell...and likely not worth having it fall inside your carboy and getting an infection.
I'd suggest playing it safe and order a real food-safe bung from online and also order a bunch of other ingredients to stockpile with to make the shipping worth your while.
