These little glass bottles are perfect for sauces, oils, dressings, vinegars, limoncello or just about anything else that you can pour. They are packed inside their own cardboard case with partitions. They include 12 black screw caps and 12 deluxe PVC heat shrink capsules, for an elegant and professional look. Apply the shrink capsules with a heat gun or steam from tea kettle. Note: some smaller blow dryers may not be hot enough to shrink these.
