Goldwell Top Chic HELP!?

So I have one of those bosses kinda like Miranda Priestly from The Devil Wears Prada, and she lives in the US for 6 months out of the year, and out of the country for 6 months. While she is in the US she goes to her regular salon and gets her regular hair treatment of Goldwell Top Chic of 7nn 30ml, 7gb 15 ml, and the 20 volume lotion. My job is to find these colors so she can travel with them and bring them to salons around the world that don't use Goldwell products.

Here is where it gets tricky. She insists that what she used to buy is a large plastic bottle of the two colors, and what ever the volume lotion comes in... All I was able to find on the internet is like a small tube (one use) and a larger metal canister (six uses). My boss refuses to believe that those are the only two options, because she insists that she has bought an even larger "plastic bottle".

So if such a bottle exist, where can I find it?! I am desperate here. And if this mystery bottle does not exist, how can I prove to my boss that it doesn't exist.

Thank you so much!!!
