Sand stick Wuta 100/180

Wuta 2nd generation abrasive (corundum), double-sided file for processing the leather edges. It has a fairly rigid base, and is designed specifically for leather crafters (do not compare it with similar nail files). When using does not require rigid base as for sandpaper. Durable enough.

It has two grains from different sides: #100 - coarser for preprocessing, stripping and forming of the edge, #180 - for finishing or for painting.
