you need it like air January 2, 2016
Reviewer: Anonymous Person from Trois-rivières, QC Canada  
as an homebrewer you never have enough rubber stopper wathever size it is. You want a 1 gallon cherry wine or a test batch go with the no 5, you want a 5-6 gallon go with a no 6.5-7 (depends of the carboy)

Best price around August 26, 2013
Reviewer: Dan from Aurora, ON Canada  
The construction is standard and this will last a very long time with minimal maintenance. As is usual with OBK, you can't beat the price.
