UStar Narrow Flat Polishing Files - Complete Set – Both Files (Best Value) is backordered and will ship as soon as it is back in stock.
Reach into tight recessed gaps and crevices on your Gunpla and scale models with these UStar narrow flat polishing files. The slim wooden-handled files are built to clean up seams, sprue marks, and hard-to-reach details that wider tools cannot touch.

- UA90682 — grits #800 and #1200, for fine finishing.
- Complete Set – Both Files (Best Value) — both files, covering the full #400–#1200 range.
- Experts Seam & Finish Kit — the file set plus DSPIAE tinted gap-filling CA and a polishing sponge: fill the seam, file it flush in tight spots, then polish the surface smooth. The complete pro-level seam-removal workflow in one go.
