16PCS 320 Grits Sanding Sponge Fine Coarse Sanding Block, Washable and Reusable Wet Dry Sandpaper Sponge， Sander Sponges for Wood Drywall Metal Wood

These sanding sponges are a must have for smoothing down primer. I like to use these on the entire surface that I've primed, or just on places I've spot primed over a patch, so once it's painted over, you can't tell anything was patched. These are good quality, I get a lot of use out of them. Once the grit wears down I still keep them and use them on things that need an even finer grit. These make sanding trim easier by pressing it into the contours. Overall these are a great value.

These seem to be good quality... I did some sanding on a guitar fret board. They are thin, but springy, and work well. I can see myself using these often.

These are perfect high density grit sanding sponges. They easily deform to a subject and have the capacity for easy wet sanding of finishes. They appear to be quality sponges and quality sanding material.
