They are ok. But I would invest in some nicer towels. I have the previous generation costco MF towels and one day I accidentally grabbed one and I saw a scratch right on the black sail panel of my camaro happen right in front of my eyes. The costco towles I only use on glass, wheels, door jambs, underhood and other inconspicuous areas. I have some nicer towels from another company that soft. The double soft towel on here is amazing as well.
