The DSPIAE SS3‑400 set includes five 3 mm-thick sanding sponges with ultra-fine #400 grit, ideal for polishing and refining surfaces on plastic models, resin kits, and medium-sized components. The thicker foam backing conforms to both flat and contoured shapes, delivering controlled smoothing and a clean finish.

• #400 ultra-fine grit for intermediate smoothing and surface refinement
• 3 mm thickness offers sturdy backing and ease of handling
• Pack of 5 reusable sanding sponges
• Compact size suitable for hobby benches and travel kits
• Foam backing ensures consistent pressure and avoids digging into surfaces

Tip: Slightly dampen the sponge before use to reduce clogging and extend lifespan. Replace when the grit wears smooth or becomes less effective.
