Coke is it. And that was crappy ASMR.
LOL, so it’s definitely not obvious to those unfamiliar with these girls. I take the imperfect recording of ASMR as being part of their tongue-in-cheek nature. They are audio tech savvy. The first thing I noticed is the unusually high amount of reverb they added, so it sounds “overdone”.
They’re also conscious of the potential negatives of “giving in” to profiting from product placement.
