Sand-Flee Uni-Sanders (aka curly or pre-assembled mops) are a versatile sanding system for a variety of materials and applications.
The sanders come shrink-wrapped in 50, 100 and 150mm sizes but expand in size once 'broken in', ie used. Different grits for each size are available. The sanders fit to Sand Flee drum sanders, but also to a drill press or a lathe.
The video below has more info and shows them in use. Check out Andrew Potocnik's review in the September issue of Australian Wood Review.
