All of the towels I use are the culmination of many years of trial and error. As I'm sure you know, microfiber towels aren't cheap. I'd be ashamed if I actually added up how much I spent to get to this point. I know I can save you a lot of time, energy, and money by giving you access to buy exactly what I'm using on my cars.
I bought and thrown away more high piled, plush towels than any human should ever have to do. They inevitably end up linting and just push liquid around. These are a very high-end version of an extremely simple towel. I use these in four different colors just to denote which is for what purpose.
Number I have in my cabinet: 20.
Note: Since I buy in such volume, I'm able to get all of us better pricing than you'd get on your own. I sell these towels at the same price that you would pay if you bought them in bulk 25+.
