I just checked and I can't find them on ebay anymore either.....I bought these about a year ago on ebay and the guy was selling 12.5 grams ones but I messaged him and asked him if he had any 7.5 gram and he said yes, so I bought 2 of them and one of the 12.5 grams ....I used both 7.5 but still have the 12.5 left....
