No more sore fingers from those tight, hard to reach places. The Teardrop sander can be used to sand in tight curves, inside corners of all angles, and almost any other hard to reach area. This works with regular or PSA sandpaper. When using the adhesive sandpaper, just peel the old stuff off and stick the new stuff on. This will wash up without deterioration of the rubber, which also makes it ideal for wet sanding applications too. Available in 2 1/2” (Small) and 5 1/2” (Large) lengths. Diameter is approximately 1 1/2”.
