Here at Esoteric, we are picky about glass towels (and everything else!), but specifically how the glass towels we use absorb grime and hold up over time. We sourced these towels from MaxShine and we put our name on them because of how well they perform, how nicely they glide across the glass when using, and how long they last. We've been testing and using these for over a year, and we can definitively say that these are THE best glass towels on the market, period.
