Medium/Medium Abrasive Sponge 2-3/4" x 3-3/4" x 1"

SIA all-purpose sanding sponges feature two different abrasive grades. They are more durable than sandpaper and can be used for both dry and wet sanding. The sponges have right angles, offer a high material removal rate, and have a long lifespan. Their foam backing provides flexibility, making them well-suited for sanding contours and curved surfaces. The structure consists of aluminum oxide applied to a sponge.
