I was just wondering about the bottles that come with the ZFX kit. There are 3 white ones and a blue/purple one. Are all of them 2oz bottles? Why is there a blue/purple one?
All ZFX bottles are 2 ounces. I beleive the reason the first bottle in the kit has a blue top is because that's the bottle that contains the ZFX dropper which is easy for both Sal and the customer to see. I guess the blue top is used to call your attention that there is acutally a 2ml vial inside. Maybe if it was white, like the rest, people wouldn't even notive the ZFX and feel jipped....
There's no difference in any of the botles though...
This is probably for packing and shipping identification. The last QC person just needs to look at the blue capped bottle and verify that the small ZFX vial is present and that only one blue-capped bottle with ZFX is in each set.
