I got tired of the expense of the small blue towel rolls or the blue "rag in a box". Bought a roll of these and the wall mount and yes, they will last me a long time, and that is EXACTLY what I wanted. Cost wise, they are considerably better than the smaller options from the local auto parts mobsters and I can use them in my auto and wood shops because of their durablity. I just toss the greasy ones instead of using cotton shop rags (that won't absorb water or coolant because they are so permanently soaked with oils). Already bought a couple backup rolls and a wall mount for the wood shop space.
