3吋 實心魔鬼氈 MIRKA ROYAL PREMIUM 白色研磨片 400目

I’ve been using these 400-grit discs for fine sanding between coats, and the hook-and-loop backing holds perfectly on my sander. They’re cutting smoothly without clogging up too quickly, which is exactly what I needed for finishing work.

Finally, a pack of fifty 3-inch discs that actually last through multiple sanding projects. The hook-and-loop backing holds tight even on my orbital sander's pad, and the 400 grit leaves a perfectly smooth finish.

Been using these 400 grit discs on my air sander for final finishing on hard epoxy primer, and they cut clean without clogging up too fast. The hook-and-loop backing holds firm even at higher speeds, which saves me from constant disc changes.
