Will these fit my bottle?
Here is an easy hack: Take a cap off a two liter soda bottle. Test it on your bottle. If it fits, it is the same size as this cap [but ours has much better threading!].
Caution: Some 8oz clear Boston rounds have a 24mm mouth. Some 32oz Boston round bottles have a 33mm mouth. Please measure your bottles before ordering. If you are buying replacement caps for Cornucopia Brands bottles, you can always message us to check.
Some typical bottles this fits: 8oz amber or cobalt; 16 oz amber, clear or cobalt; 12oz syrup bottles, 12oz woozy sauce bottles, 32oz amber old style; liquor bottles/Jack Daniels, wine bottles with screw cap style
Size 28 mm diameter [measures inside diameter of cap matches outside diameter of bottle mouth]
