I have 9 @ 5 gal carboys to sell. 5 have fluted tops that require a 3" bung - purchased from Abbott Labs in NE Illinois that were previously used in drug development.
All are glass and all are in excellent condition. 4 of the 9 are the standard water cooler style.
Local pickup preferred but will ship if you pay the costs. email me if interested at firstname.lastname@example.org
