The Only Grit Where Every Series Shows Up

Every grit collection in the FastPlus lineup has at least one product series missing — except 320 grit. At 320 grit, all 11 products across every series carry this variant. The F65 and F25 that skipped 220 grit are here. The PuroFilm 119H and PURO Ceramic H&L Roll that skipped 240 grit are back. The BN38 SiC wet/dry sheet, the PSA roll, both strip lengths — all present.
