NOTE: The soda pop bottle caps I have listed are guaranteed to be 100% authentic originals. They are all unused and new old stock unless otherwise noted. Because I cannot picture every cap, the picture above is representative of what you will receive and yours will be in the condition stated in the description. Thank you for your purchase I appreciate it.
