The Tamper-Evident Bottle Cap helps ensure that the item the customer purchased has not been tampered with. When removing the cap from a bottle, the tamper-evident band at the bottom of the closure breaks away, leaving a plastic sealing ring. The outer sides of the cap are ribbed, and the inside is linerless. The bottle cap creates a secure closure to prevent leaking. Fits: liquor and glass flask bottles, syrup bottles, glass beverage bottles, and glass sauce bottles that have a "Kerr finish" - Black; Polypropylene Plastic - Diameter 28mm - Sold per each
