M4 Linear Sander Pen

Remove nub marks, smooth seams, and refine hard-to-reach details. The M4 Linear Sander Pen brings versatile sanding to your workbench for plastic model kits, resin garage kits, and 3D-printed parts.

Quick Pad Changes with Hook-and-loop Sanding Heads

Peel off the used sanding pad, press a fresh one into place, and keep working. Both editions include 2 Square Hook-and-loop Sanding Heads, so you can dedicate one to Grit #1000 and the other to Grit #2000.

Less Preparation. More Time for Your Model.

• Quick pad changes: Hook-and-loop attachment makes replacing compatible sanding pads simple.
• No manual cutting: Matching Pre-Cut Sanding Papers attach directly to the standard heads.
• Three head shapes: Triangle, Stripe, and Square heads help you work on flat surfaces, narrow recesses, and small details.
