They debuted about 2 years ago, have been getting pretty decent ccv recently (like 2k+) and are pretty well-connected (which you wouldn't know going by their channel, but I've seen them appear on other people's channels several times).
They are not my favorite pair, but the most underrated pair that is still active imo.
