These demijohns are being offered at a discounted price as they were manufactured with a slightly oversized ovaled shape to the top section of the neck and so are being supplied complete with two large cork bungs - one bored to take a standard sized airlock, the other solid (unbored) to be used if storing the brew in the demijohn when fermentation is complete.
The size of the bungs being supplied with these demijohns are 29mm base diameter x 34mm top diameter, and they are 37mm high. One is drilled with an 8mm hole for the airlock, while the other is solid.
