these are high quality brushes at a reasonable price. I have used them wet and dry. great for exterior emblems, moulding edges, trim, grills and paint. also good for interior work for dust etc but I have only used these dry for that not wet like to clean leather- they might be too soft for that. but don't worry about these scratching your paint- I used them on my black car and then went over the areas with a light and no scratches!!!
good size selection, handles feel good in your hand , and bristles did not fray or come off the handle. if you are looking for a stiff brush- look elsewhere.
my two cents
