Bottle Caps are sweet tablet candies made to look like metal soda bottle caps in grape, cola, orange, root beer, and cherry flavors.
Bottle Caps have a tart but slightly sweet taste to them, not wholly dissimilar to Smarties Candy Company's Smarties (Rockets outside the U.S.), SweeTarts or Runts, but with soda flavors and altered shapes.
They currently are available in purple packages weighing 0.73 oz (21 g) and containing approximately 24 pieces.
They also can be purchased in a box containing 48 packages, or in small individually wrapped pouches of three candies, which can be given out as Halloween treats in the U.S.A.
There was also a time when Willy Wonka Co. made Fizzy Bottle Caps.
