You will receive 12, factory sealed, individually wrapped Nuby Wide Replacement Spouts. These spouts measure approximately 2 3/4 inches across the widest part of the spout. They ONLY fit the Nuby 10oz handle cups and some smaller glass mason jars as shown. These do not fit the wide mason jars, just the standard ones, even though these are the Nuby wide replacement spouts. They are made of 100% medical grade silicone, are clear and are bpa free.
