I have no idea what to say about these bottles. I bought these for a friend many years ago to go in her Coca Cola machine I just never got them to her and that was about 25 years ago so time to go. IF you buy six of them I will include the cardboard carrier for them. The shipping will be a little tricky but depending on how many you buy the cheaper it will get two will probably ship for about the same as one so the answer is yes I do combine shipping. Here is something for the collector. Thanks for looking and good luck bidding.
