Gold with Black Grapes PVC Foil Capsules give your wine bottles a clean, professional look. These capsules will shrink when you dip them in boiling water, hold them over the steam of a tea kettle, or blow on them with a hair dryer. Make sure to be careful when shrinking the capsules to the bottle. Note: The capsules fit standard wine bottles, use the large capsules for bottles with a flanged top.
