3M 2601 Ultrafine Softback Sponges, Twenty-Pack
The 2601 Ultrafine Softback sponge is designed for hand sanding around contours and restricted areas such as door jambs and handle recesses. Its foam backing conforms differently from a rigid sanding block or machine disc. The listing identifies a twenty-sponge box; the range photograph displays several grades and does not turn this order into an assorted-grade kit.

Before ordering
Select the Ultrafine grade using the repair or coating specification and verify substrate compatibility for wet use. The stated range does not make the sponge equivalent to every P800 or P1000 sheet. Flexible foam does not guarantee against coating damage, and no machine-disc attachment is specified.
Product questions and answers
Does the range photo mean several grades are included?
No. This listing identifies the 2601 Ultrafine option with twenty sponges per box. Confirm that exact grade when ordering.
Can I attach this sponge to a Hookit sander like a round disc?
It is described for hand sanding with foam backing. No machine-disc attachment is specified; choose a tool-specific abrasive for powered use.
Is Ultrafine automatically interchangeable with any P1000 paper?
No exact equivalence is established. Use the coating maker's specified abrasive type and grade, particularly when comparing foam-backed products with paper discs or sheets.
