24 Pieces Blue Sanding Sponge Ultra Grit Drywall Sanding Blocks Washable Reusable Sponge for Ceramics Models Wood Crafts(220 Grit)

Used almost the whole pack to sand kitchen cabinets I painted. Cabinet went from the oldschool Golden Oak with oil clear, to clean white, and these helped sand every angle and curve on the profiles. The sanding sponges are very flexible, you can fold in half no problem, they don't tear apart. They sand pretty well too, I was pretty impressed, don't expect any crazy rough sanding out of these, definitely grit 400

After using the 3m blocks from the big store I was in search of a block with a softer sponge backing. This is what you want for sanding trim. I just finely sanded 400 board feet of 3 1/2 in tall base board that I pre primmed with oil based Kilz. It took 6 pieces of 220 grit sponges from this pack. The durability was better than I expected, even though the pads appeared clogged with dust they continued to do what I wanted which was knocking down the high stuff without removing all the primmer. Maybe somewhere in the description it says these are double sided but if it doesn’t they in fact are. I did try to use a spray bottle to clean one dirty pad and it did. However I didn’t let it dry enough and it clogged right away. For the price, quality, durability, and just right sponge softness these are what you want for sanding trim. I totally vouch for the 220 grit on pre-primed oil base primmer.

These have been the best sponge sanders I've bought. Grit on both sides, too!

Son de muy buena calidad y muy flexibles, exelente para gabinetes y molduras a la hora de lijar entre capas

Great for sanding tumblers!

Redoing an older home, and I have tried different sand sponges on my old wood trim. These are by far the best!

I received what I ordered, but I found these unusable for my needs. I always use sandpaper with a stiff sponge or solid backing, but the sponge backing on these are way too soft. The sponge is so flexible and soft that I would have preferred the sandpaper without it. A layer of 1/32 cardboard would work better for me. Try and learn I guess.

These sponges are great, softer and thicker then the 3m, they're pretty durable, not as durable as the name brand but I feel they are a great deal if you're doing any lacquer work or even finish sanding prior to staining.
