My employees love all size of these for interior detailing, the variety pack is an awesome value!

These work Great for small vents and a variety of small areas to reach and clean. There are a variety of sizes and shapes to tackle any job. I did notice that after opening a package within a week all of the white foam is turning a brownish color. Doesn't seem to affect quality but I like the white color so I can see the Dirt I am removing from different area's.
