A.O. إسفنج رغوي سميك 1" 2 3/4" × 3 3/4" (أربعة أوجه)

Finally found a sanding block that doesn't flex too much on curved edges, and these hold up to wet sanding without breaking apart. The four sides are a lifesaver for getting into tight corners without swapping pads.

These things are chunky at a full inch thick, and the four-sided design means I get a lot of mileage before I have to flip to a fresh face. The 2 3/4" x 3 3/4" footprint fits my hand perfectly for detailed sanding.

I’ve been using these 1" thick foam sponges for my wet-sanding projects, and the four-sided design saves me so much time flipping between grits. The 2 3/4" x 3 3/4" size fits perfectly in my hand, too.
