A little bigger than the swizzle stick sanders but at 1/4 wide they are small enough for smaller spaces and finer details. Work great for sanding sprue attach point material left after cutting parts loose with a sprue cutter (although the finer versions are nicer for that). There are 2 grits on each one although they aren't marked as to what grit it is. Comparable to approximately 220 & 280. Last a long time and can be trimmed if needed.

Great file, good size for tight areas and a must for modelers
