I love these stoppers. They stay put in the carboy mouth. Unlike the silicone universal types.
Perfect fit in 1 gallon carboys, Doesn't slip upward like the silicone universal ones .
These are perfect for the 1 gallon glass carboys or jugs
Works on Carlo Rossi 4 L wine jugs, Water jugs, 1-gallon carboys. Those are the reasons I purchased the item
